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.
