Hello, my strain is UV screw top jar
The jar is beautiful! Heavy and rugged, and I love the fact I can write on it, clean it off when I put a new one in it and write that one in. I like the small ones that I can grind some of a strain, enough for a few days or a week, and carry it with me or set it on the shelf with my bong, ready for the next session. The lid has a very thick gasket in it, to be smell-proof.
