a buddy of mine used these ends to a wooden dowel rod that was hollow and glued them in those. he had like 50 beards and many were too fat to use shotgun shells so he improvised. then strung them through a string that was pinned from one corner of the room to the other. looked pretty sweet and he and his son are still addin to the string. wish i could show pics but he lives 1 hour away so thats not an option. ill look around and try and show you what those little cups look like.
