- All of the cache containers I have found have been primarily made of plastic. Has anyone found any cache containers made from glass? Is glass taboo as a container? Some glass is thick and are very water tight with rubber seals. How about tin? ie cookie tins, decorative tins? Too susceptible to rust?
