This is such an amazing little storage container! It's a tad bigger than I expected, but it's still such an amazing container! It's about 2 inches across in diameter, but it's about 1 and a half to two inches tall. It's glass with a glass or plastic top. I believe the description said it's plastic, but it feels like glass. Overall, a really perfect storage for what I need!

The jar is great and looks good. I would and have recommended 420 science jars to freinds and family.

This is my fourth screw top container, I have two of the medium and two large. Both hold for weeks without a problem.

Very easy to use
