Smaller and more expensive than artisian deskmats
Color: Black
These are slightly smaller than the standard artisan deskmats and double the price.. It's also about half the thickness, so there's not as much padding. This isn't a huge deal. if the felt is on the bottom, it doesn't grip to the desk very well. The wireless charger is okay, but I found it bulky. Having a small dedicated 3 in 1 charging stand was more convenient for me. If you have a heaver mechanical keyboard, you won't be able to lift this thing to see underneath it. Overall, this is an okay deskmat and it'll serve it's purpose when I'm washing my regular deskmat, but not my favorite.

Don’t bother, not worth the $
Much smaller in person than it appears. Looks more like a piece of coral than a tree. I got this to display some ornaments for sale at craft fairs, but it’s so small, it looks silly with the ornaments on it. Super flimsy, made of cheap plastic. Definitely not worth $14. Will be returning.
