I really am surprised by the quality of the desk mat. Good side stitching that has help up through multiple cleanings. More importantly the print quality of the mat is excellent, I use a simple HE laundry detergent and a tooth brush to clean the mat, no staining and no fading.
For the design itself, my nephew loves the design, there is so much detail and text, he even got an art tube to travel and protect the mat whenever he uses it.
Great quality, and nice to the touch. It's a good size and the print is clear. The little snippets of info and the diagrams provide a fun little bit of insight into NASA history. I'm happy with this.
