Needed just one of these for an old light that I broke the lens out of. Only thing I could find was a 10 pack from DX. If anyone could use some of them let me know and we'll arrange something. I have no use for the extra 9 that I had to buy, lol.
Also have 1 28.6mm x 2.84mm lens that I bought on accident from FlashlightLens.com and it fits nothing that i own, so let me know if anyone needs it!
