I am looking for something that is made of a nice, hard, durable plastic and is just a little bit bigger than an altoids tin. This is for a bike repair kit. I dont want metal, and if the plastic is see through that's ideal but not mandatory. Anything out there you can recommend? This will hold miscellaneous bits like extra brake pads, chain links, screws, deraileur hanger, shoe cleats, etc... Anything out there exist like this?
