CARL RM-12 12-Inch Cutting Mat for all 12-Inch Trimmers,Gray

Fits perfect and works great!

Worked great. Was the missing piece to to make great cuts. Didn’t know it was missing until looking online for it not cutting.

I tried another brand, but will stick with Carl brand matt for Carl trimmers. For some reason, the non-Carl brand cut into the matt; and they did not last as long. Best to buy these.

The blade runner was an exact fix, working great

I have had my Carl cutter for over 25 years.. I replace the blade and this mat every couple of years & it's still going strong. Highly recommend!

Works well, was a little long for my cutter for some reason, but was able to trim it down. Just added some sticky to one side so it would stay in the slot.

These are a replacement part for what I feel is the best and most accurate cutter for its price. I use it to cut both cardstock and 20 mil magnet sheets and the cutter works well, and more importantly, it cuts exactly where you place the edge. The replaceable mats slide in easily and last me thru perhaps a couple hundred sheets before the blade pressure cuts too deep of a groove in the mat which makes the blade slide off target. I have another "high-end" cutter that I never use because, although it can cut more sheets at a time, you cant accurately determine where the cut will end up, and it wiggles, despite being metal. So if accuracy is important to you, dont spend alot, get the Carl cutter that this part goes to. I have had mine for 7 years.

Works perfectly.
