I had to google this to find out what this might be. The closest I could come up with is a plastic paper crimping tool. HOWEVER, I TRIED SENDING PAPER THROUGH IT AND IT ONLY CRIMPED THE ENDS SLIGHTLY. CARDBOARD IT DID CRIMP BUT I COULDN'T MOVE IT THROUGH BECAUSE IT WOULDN'T BEND ENOUGH. Anyway measurements are 6" W x 7" L x 2" D. Roller is 4 1/2"+ Long x 1" Diameter. Check out the pictures and ask questions before bidding/buying. No refund. Also understand that I have am guessing at what this may be. No refund. Check out my other items for sale.
