PROTHINGS PRORANGER cutting aid guides.
 
These small but extremely helpful cutting aid guides, are supplied as a pair an R & an L. Use the R for cutting from left to right & L for cutting right to left, this makes this set very versatile.
 
Both feature a strong built-in magnet, allowing most 9mm knives to magnetically hold preventing slippage or movement during the cutting process.
 
Both guides are of equal size and create an approximate 11mm overlap of film, this allows for a clean neat cut.
