Put them for sale here in lots of 5 to 10....complete descriptions, etc. I am certain that you will probably sell most of them without any hassles. If one shoots 4x5 then there is always the temptation to pick up a few more holders, "just in case"....of course, "just in case" (thankfully ) usually doesn't come to pass, and so one is left in the same situation that you find yourself...i.e., many holders in the closet or drawer!
