I used to house my A.C. strikes in metal and/or plastic hinged cases that were originally intended to be used for 35mm 2x2 slides. The silver strike capsules fit perfectly and there is a convenient hinged handle on the case to carry, or to pull off a shelf. I believe each slide case held something like 80 strikes. My duplicate strikes were housed in empty heavy-duty red cardboard boxes that were intended for 2x2 cardboard coin holders. They come in two sizes; single row and double row.
