Review on ATD-360 Advanced Tool Design: 350-Piece Stainless Lock and Flat Washer Assortment - Ultimate Hardware Solution by John Frazier

I'm not an expert on shims but I think shim is shim as the function of a shim is pretty simple. Although the organizer broke in one spot, I liked that the baffles were secure, which keeps the washers in place. I also liked the dimensional grid and the fact that the washers were in pouches.
