Here's a pic of a couple of round tins that'd work for a kit. The larger tin (4"X1 5/16") came with a flint and steel firestarting kit a friend gave to me. It would have to be taped to secure the lid. The other tin (3"X1") is the military issue sunburn prevention cream.<br><br>http://www.hunting-pictures.com/members/archer071/tins001.jpg
