    Will the package have any references to 420 on it?

    All orders are sent in a plain box. Orders sent via USPS Priority Mail simply show our return address on the label - no company name. Orders sent via UPS will have 420 Science in the return address section, but no other references.

    Why is 18+ signature required for delivery?

    In addition, this provides better tracking and delivery verification. If you’re worried you won’t be available to sign please sign up for UPS My Choice.

    We ship to the United States only. We do however have distributors all over the world.

    420 JARS

    Do 420 Jars come with lids - what are they like?

    Yes! Every jar we sell comes with a lid. And you can purchase replacement lids here.

    The Classic Series of Pop Top 420 Jars have a glass lid with a plastic gasket ring to seal in the freshness.

    Clear and Amber Screw Top line of jars feature a black screw-top lid that provides an equally tight seal.

    Wide Mouth Jars come with a lid we designed ourselves! It’s food-grade silicone which offers double-wall protection to ensure maximum freshness.

    The UV Jars are fitted with a black screw top lid.

    Concentrate Jars also feature a black screw top lid.

    The Tincture Dropper lids have a glass pipette that reaches almost to the bottom of the bottle.

    The Latch Top Jars have a glass lid that hermetically seals on to the jar with the assistance of a rubber gasket.

    Our 1.5 and 2.5 Gallon Jars feature a brushed metal lid with a gasket seal.

    And finally, our 1 liter UV Jar has a glass on glass lid

    I need a replacement lid for my jar.

    You can purchase replacement lids here. Not sure which size you need? Compare the dimensions of your jar to the dimensions we give on the product page for the jar you think you have. The silicone lid is the same for the small, medium and large Wide Mouth Jar.

    Why should I use a 420 Jar?

    Several reasons. Number 1 - Freshness. Herb isn't cheap; don't let the quality degrade by storing it in a plastic baggie. Number 2 - Presentation. 420 Jars look good and show you have a little style and a taste for the nicer things in life. Number 3 - Smell. 420 Jars help contain that infamous herb odor. Want to know more about storing your herb, check out this video from High Times.

    What's the biggest jar you sell?

    The 2.5 Gallon Jar is our very biggest and holds 1.25 lb. of herb. The Large Latch-Top Jar is our 3rd biggest and will hold up to four ounces of herb.

    Aren’t your jars just decorated with stickers?

    No way! The designs on our jars are a special glass decal which is applied by hand in our warehouse here in Austin, TX. The decal is then fired on to the jar in a kiln at over 1000 degrees. This permanently adheres the design to the jar for life so it will never chip or wear off. This also means the jar is dishwasher safe for when you’re ready to clean it.

    I want to suggest a jar logo

    We have amazing in house designers who are always working hard on new jar designs, but we’re always happy to find out what kind of new designs you’d like to see or check out something you’ve created and would like to share with us. Send it over to us at Help@420Science.com

    Can I get a custom jar made just for me?

    Unfortunately, there's no cost-effective way to do just one jar. If you're interested in getting 144 or more jars with your own design, we can do that. We can usually work with you to put your design on a few different sizes or styles of jars. We need your artwork in a vector file format, lead time is about four weeks and we require a 50% deposit. If you’d like to find out more or are ready to move ahead with a custom order please email us at Custom@420Science.com

    Can I buy a blank jar?

    Totally! Use this link to go buy yourself all of the blank jars your little heart desires.

    Are your jars smell proof?

    All of our jars are air tight. However, the very strong odor of some things just cannot be contained! Plus handling what’s inside the jar, then handling your jar can leave a residue on the jar that will give off odor. We do not recommend relying on our jars to conceal scent. We hope you’re able to use your jar in an environment where you do not have to worry about smell and can proudly display your stash in an aesthetically pleasing way. If concealing smell is your #1 priority, we recommend going with other containment options that guarantee scent concealment.  

    Can I get a different design on the jar that comes in the MegaPack?

    Yes! At check out in the comments section, please tell us which design you’d like on your jar.

    My jar broke!

    Why were you treating it so carelessly?!! Just kidding, we understand that sometimes shit happens right after you just enjoyed a little bit of the lovely stash that was in your jar. If you purchased it directly from our website, it’s covered under the lifetime warranty and we’ll replace it! Email Help@420Science.com and attach a photo of the broken jar. Let us know the original order number, your name or the email you used when you placed the original order so we can confirm you did in fact purchase this jar from us. Once we have that information we’ll send you instructions on how to pay the replacement shipping. The replacement shipping is $5 if you’re in the US and $15 if you’re outside of the US.

    420 SCOPE

    Does the 420 Scope come with batteries? What kind?

    Sure does! It comes with 3 SG3 button batteries that are long-lasting and easy to replace. They're common watch batteries and available everywhere (places like Target, grocery stores, etc.) You can also purchase them from us right here.

    Why should I use a 420 Scope?

    So many reasons! One is to compare different types of herb; for the first time you'll actually be able to see the trichomes and know exactly what you're smoking. Growers like the 420 Scope because it allows them to check for mites and mold, plus know the optimal time to harvest. Then there's the fun factor - it's a cool gadget and lets you see herb like never before. Zoomed in at 60 to 100 times magnification, some of the views are just incredible.

    How do I use the 420 Scope?

    We recommend that you begin by setting the zoom at 60 and the focus all the way to the right. Put your specimen on a flat surface and turn on the 420 Scope's LED light. Then rest your 420 Scope directly on the herb and adjust the focus until the image is sharp.

    What makes the 420 Scope better than other microscopes?

    Several things. One is that the 420 Scope uses a bright-white LED light (instead of regular "yellowish" bulbs) and will illuminate your herb for optimal clarity. In addition, 60 to 100 times zoom is the best magnification to inspect the trichomes. And of course, its size - the 420 Scope is handheld and will fit in your pocket.

    How long is the cable on the USB Scope?

    The USB Scope has a 52" USB cable that connects to your computer. Power is supplied by the USB cable, so you don't have to worry about power outlets or other cables.

    Where can I download the software for the USB Scope.

    Right here.

    I can’t figure out how to use the USB Scope.

    Sorry you’re having trouble. Regretfully we do not offer technical support on the USB Scope. Have you installed the software? Restarted your computer and tried again? Have you tried it on a different computer? If it’s still not working for you, we’re happy to take it back. Please follow the instructions on this page for making returns.


    What is RezBlock?

    RezBlock is an all natural resin blocking water additive that prevents resin from sticking to your water pipe! Seriously, it keeps resin from sticking anywhere that the water is touching the glass in your water pipe!

    What’s in RezBlock?

    RezBlock is a proprietary blend of fruit extracts, vegetable glycerin, purified water, and citric acid.

    How do I use RezBlock?

    Starting with a clean water pipe is best. Fill your piece with water, add 4-6 drops depending on how much water your pipe uses and then take a dry pull to mix. Now use your piece as usual. Change the water as often as you would normally and watch your glass stay clean!


    What’s the return and exchange policy on pipes?

    You can exchange or return unused glass within 48 hours of receipt. If it has been more than 48 hours since you received the item it’s yours forever.

    What’s the warranty on the pipes you sell?

    We do not offer any warranty on any of the pipes we sell. This stuff is made of glass, be careful with it, treat it well and it will return the favor!

    I bought a pipe from you and I broke it.

    Total bummer. We’re really sorry we do not warranty the glass pipes we sell.
