LJY 24 Pieces Multi-Colored Round Aluminum Cans Screw Lid Metal Tins Jars Empty Slip Slide Containers (2 oz)

Can you put a compact mirror on the inside lid?

I would like to make product labels for these. What is the diameter across the top and what is the circumference around the outside of the jar itself?

Can these be atttracted by a magnet?

Would a couple of tea bags fit in these?
