ALVIN GBM Self-Healing Cutting Mat 12 x 18 inch | Double-Sided Green/Black | 5-Layer Gridded Surface for Arts, Crafts and Sewing - Model GBM1218

Purchased as a gift for friend who let hers in the car during a hot day. It warped beyond repair. She mentioned, good size and quality

I've used this brand of cutting mat for years and they've always worked well. I bought this small size specifically for using while cleaning up 3D prints and it's perfect. Saves the desk from damage but easily moved out of the way when no longer needed. I like that it's double sided and expect it to last a long time.

Excelente

It had my name on it so it eliminated the need to label it. LOL. That said it's done everything it's said it does. I mentioned in other reviews I was into a few hobbies. Electronics and soldering, vaping, and it's most useful application in custom plastic model kits. I bought it long before I got into Gunpla and I got the most use out of the mat in that application for allowing me to set masking tape and cutting it to shapes I need to cover from spray painting. The grid and angle lines are great for measuring and marking plastic plates as well. It acquired damage from my soldering (I absent-mindedly just set the iron on the mat and got irreparable burn holes) but that isn't gonna deduct points from the score. There were other places on the mat I can use the grid lines. If one side gets too damaged, I'll just flip it over. It does self heal from the hundred of cuts I've made into it. The one gripe about it is that it slides if you're slicing harder materials (like plastic plates), but that's to be expected if a mat has two sides. If your name is Alvin, buy it. If it's not, buy it anyway. It's a great mat.

Great size for fussy little cutting tasks. Very portable.

Matt is excellent...but whom ever ships this has a lot to be desired.

It’s perfect for my modeling work

I received 2 of the 24 x 36 mats as a birthday gift and my cutting table needed a bit more to cover it entirely. I had ordered another brand in what was supposed to be 9 x 12 and the brand was not of the quality of Alvin. These are exactly as described. The 9 x 12 was exactly 9 x 12. I also check that the markings on the mats are exact and the Alvin brand is. Even more impressive, once you line them up side by side, the distance between the markings across the mats is also exactly right. When side by side, the edge marking on one mat is 1 inch distance to the edge marking across to the next. You do need to line up the mats to be the same direction. I set the logo to be in the upper left as each one is laid out on the table. That's a very, very good indication of quality. The other brand was not even 9 x 12 - it was not quite 8 3/4 by 11 and the markings weren't properly spaced meaning they failed the 'ruler' test. I can recommend this brand without any hesitation. I did have to leave the large mats out for a full 24 hours to air out. Note: For those new to cutting mats, the dimensions of cutting mats refers to the overall dimensions and not the lengths that the markings go out to. A 9 x 12 mat will have marking lines for 8 x 11 or should have. I also recommend using a trusted ruler or measuring tape to double check any mats markings to make sure they are true. Thanks to trial and error over the years, I learned not to assume they are.
