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

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

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.

Great value

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.

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.

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.

These mats are perfect for replacing the original mat. The original mat wore out after several years of service. I should have replaced it earlier, but at least now the cutter cuts much better.

This is an OEM (original equipment manufacturer) item so it was perfect for my needs. The real find was that the price on Amazon was better then buying direct on the manufactures web site. The item meet all my requirements, and works exactly as it should. I would buy from this supplier though Amazon again.

This is a replacement piece for the cutting strip. Exactly as shown

Excellent deal and the product was exactly the one for my rotary cutter, would reccoend to anyone.
