I thought these were just black jars with cool art... but for some reason, I held one up and looked at it through the light. The most beautiful and deep cobalt blue / violet light appeared. Barely. It's been my favorite color for many years, so I was really caught off guard; the color was so amazing I almost cried. But I was also really high at the time. I ended up buying four more. 10 stars out of 5
Thick glass with the cutest designs I bought 2- the small gnome jar and the space man XL and I love them. The XL holds an ounce for my main stash and the small holds an eighth so its perfect for my go bag. The designs are very permanent and won't scratch off, plus I got stickers with my package of the 420 likes design and 420 science logo which I put on my jars so now they're extra cute.
