Carl, RM-12/4, 12-inch Replacement Cutting mat for All 12- inch Rotary Paper Trimmers (4 Pack), Gray

Good quality and perfect for my Carl trimmer!

Works as intended. Fits my CARL RT-200 12"/A4 cutter.

I am always apprehensive about buying a replacement part for something online. If you miss a tiny detail, you might be ordering the wrong part. Thankfully, that did not happen. The part arrived safely at my door, and was the exact part I needed. It fits perfectly in my trimmer and took about 30 seconds to replace. It appears to be the same quality as the original part, which lasted for years. I can say this was a very good purchase.

This really should come as a 3-pack. The one to replace the strip in the cutter and 2 more which will fit in the onboard storage. Now I'm left with an extra to keep track of when these things last forever and a day so by the time I get to where I need to replace one again it'll be long gone in the back of a drawer.

Perfect, snap right in my rotary cutter great price as well.

My Carl RT-200 rotary trimmer works great and I've had it for 2 decades. It's a great device. I'd finally run out of my cutting mats. Each one can be used 4 ways (what a great design!). Thus this 4 pack will get let me get 16 uses, each with a few thousand cuts. This will last me another decade at least.

A decent price on an attachment that's needed to keep our Carl Trimmer cutting with ease.

I want to thank the other reviewer that posted a photo. The product measurements posted on the details section are totally incorrect. If I hadn't seen the posted photo of the machine (just like mine) I wouldn't have purchased these mats. These replacement mats actually measure 14.88 L x .38 W and .13 thickness. It fits perfectly on my very old Carl RT-200 machine. The back of my machine states that the replacement part for the mat is RM-12. I was not able to find these at my local store, so I was very happy to be able to find it here.
