I keep 90% of my chips in DANSCO binders (some with the archival sleeve). The others, including Silver Strikes are in air-tites. The air-tites are the put in 2 1/2" X 3 1/2" with 2" hole cardboards. The cardboard folds over the air-tite and is sealed accross the top with a label. The air-tite can be removed and re-inserted through the sides of the cardboard. These cardboards (with slight trimming) fit nicely in a Whittman box made for SLABS (holds 20 cardboards).
