Really good mat.
This mat is sturdy and stays in place during use. I bought 2 to meet my size needs and they work perfectly. They came in a flat box, which is good as they were not rolled up. It did take a week for delivery. I was eager to have them as I had a new sewing machine and so wanted to cut something to sew up. I did have a large and wonderful mat; I wish I knew which maker. My first mat was lost to me in the Eaten fires. I first bought a mat from NOT Amazon. The seller hadn’t sent a month later. So I said buy what is reliable do Amazon. This mat is a good choice and I am pleased to have it.

Great for use with rotary cutters, but keep away from heat
I previously owned the Alvin 18×24 inch cutting mat, and I loved it. I had to upgrade to this one because I kept the previous on in the car during a hot couple of days, and it warped/crimped up on one edge and the entire thing shrunk about .5 inches so it didn’t match up exactly with the marks on my ruler anymore.This product arrived in a very large, picture-frame shaped box. It was not folded in half, but it did have a slight bend from being slumped in the box. After lying flat on the ground for several hours, the bend was gone. There was no strong odor. The mat self-heals well and doesn’t retain marks from my rotary cutter.As other reviewers have noted, this mat is exactly 36×24 inches, and only has numbers up to 35 and 23 inches with a half-inch border around the edge.I learned my lesson with transporting these cutting mats and exposing them to heat, and I plan on keeping this one in my house and away from any heat sources.12/28/15 EDITED TO ADD:I was very careful to keep the cutting mat out of my hot car or heat sources. I kept it behind my sewing machine desk in my air conditioned loft. When I next pulled it out, it had warped along the top because–I’m assuming–it was near a window. It was not exposed to direct sunlight, but the heat from the window significantly warped the top of the mat.As far as durability, the mat held up well over the year or so I used it. The only issue I had was when I cut a large number of quilt strips along the 45 degree line with my rotary cutter, a long, narrow, sliver/chunk of the mat came out along that line. The mat was still usable, but it wasn’t perfectly smooth anymore.I took away a star from my original review because, even though I like this product, it warps entirely too easily when exposed to the slightest heat. I am buying yet another one, but this time I will keep it on the wood floor beneath the rug in my craft room. Fingers crossed it lasts longer this time!

My Favorite Recent Amazon Purchase
I run a vinyl decal business out of my home and have been working on creating a better work space for completing orders. I was previously cutting vinyl on a table made from scrap wood (no cutting mat or protective surface) because it was all I had at the time. I purchased this mat to rest on top of the table so that I would stop getting splinters, dust and dog hairs in my finished decals.I must first say that I have never owned a cutting mat. My mother has been sewing for most of her life and I can’t remember her ever having one, either. So, I didn’t really know what to shop for, only that I needed one to cover most of the surface of my work table.I purchased the Alvin Cutting Mat first for the size to price ratio (it was significantly cheaper than other brands of the same size), second for the self-healing capabilities, and third for the stellar reviews it had received. After using it for two weeks, I am happy to report that it is everything others have claimed and I am extremely pleased with it. I was initially intrigued by the two-sided feature. As far as I can tell, there is no difference in the sides other than color, so I use the green for vinyl and the black for fabric. I have cut on the mat with various blades and each time the cut disappears in seconds. It looks good as new every time I use it. I’m not sure how long this will last, as I tend to cut vinyl very often, but I am pleased thus far with the results. As for cleaning, I have used a damp cloth to wipe it down once, but for the most part it stays pretty clean with the type of work that I do on it. I am not concerned about the mat keeping its shape (mine is left flat on the table 24/7), but if I do put it away at some point, I’ll be storing it flat as well; the mat isn’t flimsy but seems like it could possibly warp if not hung up or stored flat.Overall, I believe this has been my best recent Amazon purchase. The mat was delivered in a large flat box to prevent bending and the packaging was sufficient. I plan to use this mat for a long time.

Se trata de una tabla para corte de precisión bastante gruesa, se recupera fácilmente de cortes poco profundos. Se desliza poco sobre la mesa por la superficie rugosa y el peso. El tamaño es muy adecuado para trabajar con hojas de los tamaños más comunes e incluso modelado a escala como lo es armar gundams y otros modelos pequeños.

This is a great cutting mat. It may be worth noting that the product picture is inaccurate and the mat itself is very small, without any diagonal lines on it. The mat is solid and well-made, with one side a black colour and the other green. This mat looks great and works great.The most impressive thing about it is the ‘self-healing’ abilities, which are rather impressive. I have made hundreds of scratches of varying depths to see how it would hold out. The mat doesn’t completely heal from most scratches, regardless of how deep they are. However, when I have made really deep scores into the mat, they have dramatically faded to be more like normal scratches, in a matter of just a few hours. The only problem is that the lines fade off when scratched, but it takes quite a lot of scratching to affect the functionality of the mat.This is a great product that should last a while due to its self-healing properties.

Great little cutting mat, just a bit larger than a standard sheet of paper, so it works well on my cluttered desk!
