These are the tins I use for organizing my rings. They’re the same size as Altoids tins, but the surface is completely blank. I write the ring size on the edge of the tin in sharpie marker and then make any notes about good weaves, etc. on the lid. For long-term storage, I use card boxes from the local comic book store. Perfect fit!
Little round tins fit nicely inside these rectangular tins for nested storage, and eight of these rectangular tins will fit in a lunchbox tin with pliers for a complete project kit!
