Ain't injection moulding great Those boxes probably cost the munufacturer 30 cents in plactic and another 50 cents overhead to make . They have multiple uses not just for chips. Aside from the fact that they are almost see thru, great if you know what a chip edge looks like, and have a great locking system. I have been useing them to store drill & router bits for years. Got the idea from a fishing buddy of mine that uses them to keep his lures and stuff seperated so they don't get tangled up with each other. Always great to see someone come up with a new way to store and organize their chips.
Hava Good one,
