I use these 1" dia. 1/2 oz. jars from uline (second smallest pictured). 200 per case $.28 ea.
I glue them together making a stackable storage system THAT ACTUALLY STAYS TOGETHER! The lids thread on tight and hold not like the stackable crap Ive tried in the past that topples apart when you breath on them. I can glue these 3' high and beat the kids with them all day long and they stay together.
One stack for tungsten, one for brass, one for glass ect. ect.
They are really a must have for a million other uses too. 200 may sound like a lot but its not enough...trust me.
