Review on PAG Tagging Attachments for Fastening Guns by Peter Parks

I recently bought a marker from Michael's and wanted to use longer holders. The ones that came with the kit work great and slide smoothly through the gun, but they're red and only half an inch tall. They are the perfect size and transparent which is what I was looking for but the end of these clasps that goes through the needle was way too thick! Every time I try to use it, the needle pops right out of the gun. There is no mark on my gun otherwise I would be happy to share. Looks like I'll have to buy a new gun or try to return 4991 of these. Otherwise they seem to be great quality, I just wish I knew they wouldn't fit!
