Stacking Sieve Set

This is a set of 5 small sieves I made because I needed to grade a small about of pebbly sand, but obviously, they can be used for what ever you like.
There is a 5mm, 4mm, 3mm, 2mm and 1mm unit, and they all stack together.

Edit: I also just uploaded a bigger set in 2, 3, 4, 5, 6, 8 and 10mm that are wider and deeper
