The only solution that I can recommend is air tights which take up alot of room and are more expensive. And the binder solution is only one method I know of. Its 2 1/2 X 2 1/2 white cardboard holders with mylars windows. 12 go into a vinyl page. 10 pages fit in a 2 inch 3 ring binder nicely. So you can put 120 chips in a binder.
CHEERS!!!!
