Diamond Dish Drying Mat For Glasses and Cups - Black 5 "2nd One Purchased!" Gill 31 October 2018 I've got two of these. I've got granite worktops and I don't like draining racks on the side, particularly as my sink sits in an island unit. Therefore when I do have to wash up items such as knives and other bits which I don't put in the dishwasher, I use these and I switch them around so that one is in the wash and the other on the side. Very absorbent and they keep your worktop nice and tidy.
