Am very happy with the mat. It was the exact color I was hoping for and great quality. I was worried it might get damaged in shipping but it was packaged extremely well. An elephant would have had to stomp on it to damage it inside the package. It did take a while to arrive but it came when they said it would. I would highly recommend.I ordered a 14x17 mat with a 10x13 opening to use with a 14x17 frame from the same seller. The mat is just as described and, as far as I can tell, great quality. It's probably better quality than I would have gotten at Michael's or Blick (where I first looked but decided against it because of the expense). One word of advice if you don't frame art often, definitely take advantage of their custom opening sizing. The document I want to frame was just shy of 10x13 and the seller reaches out to inform you that the mat will be cut 1/4 inch smaller (9.75x12.75) so that the document won't fall through. I didn't care enough to double check the size of the document because I knew it was "close enough". It's just barely fits because the document I have is probably 9.8x12.8. So I'm happy with it, I just have to be careful with assembly.tldr: Seller gives a personal touch, great quality, great price, ships on time, take advantage of their custom cutting!Ordered direct from vendor and after contacting them they are able to cut the opening to the exact size I needed. Arrived quickly and looks great. 5/5 will def be making another purchase soon!I asked for custom sizing and my order arrived within a few days. Great Product madeOf quality material. I amMeasuring for my next order!!I got the Fountain Blue color. I was nervous what it would look like, it's great. A very pretty shade, subtle.I was nervous because my frame is from a different company, so I didn't know if the mat would fit into it, but it does with no issuesPleased to find the option to have the mat opening cut to a different size; followed ArtToFrames seller instructions to send a message within 4 hours of purchase. The item was ready and shipped promptly within a couple of weekdays so I was able to receive a custom cut mat in about a week. Color looks just like I expected from the listing.I got this mat along with a silver frame from the same seller. The seller was kind enough to custom cut the opening in the mat to fit my picture precisely. Also it came all set inside the frame I purchased, so I recommend ordering a frame from this same seller if you are ordering this mat. It looks great on my wall. I love this shade of blue.Expect to pay for a high quality product. That is what this is.Every single measurement was exact.As a quasi semi- pro photographer it is important when displaying prints.You get what you pay for.
