Review on Marble Coasters Set Of 6 - 3.5 Inch Square Coffee Mug Mats For Kitchen Caddy And Office Pot Drink by Richard Koh

I will use these coasters. I actually have marble coasters like this in a round shape but these are better because they have a non stick backing that is very nice. The coasters don't slide around, making it more stable to put a glass on. These can also be used to rest a dirty spoon while cooking. All in all I like this set. There are a few cons: the corners are not all uniform. Some meet in the perfect 90' angle while others have a more flat joint in the corner. This does not change its function, but it is noticeable. The other thing is that I was hoping these would be giftable, but they arrived an a tight styrofoam storage box. This protected them but it is not attractive. I would have bought them as office holiday gifts had the packing been more presentable. I could move them into a gift bag, but I am afraid they might be fragile for that.
