Extra heavy glass. Good quality. Joint would be better if it was ground.
So I've had this rig for quite a while now, and something you should know is that I'm TERRIBLE with glass. I always break it one way or another. I'm incredibly too clumsy, so having a piece stick with me this long is insane. I had it for over a year before I finally did it in. I immediately ordered a new one because this rig is durable, functional, cute, and easy to travel with. Highly recommended!

This piece of glass in my case turned out terrific. It's a smaller piece which often means diminished air flow but this particular one is certainly adequate. The glass is thick and heavy and overall it's very stable. I would really recommend using it for dabbing only as although there is decent filtration a flower hit is going to be really hot as there is only minimal cooling. Add a ****** and you've got a really nice low temp dab rig that won't break the bank. 420 Science comes through again.
