|Used as coasters, place cards, for wine-tasting notes, to doodle while you imbibe, or simply jotting down messages next to your phone, Coaster Notz are made of non-toxic silicone. They can be personalized time and again using a ballpoint pen. Offered in a variety of colors, each pattern comes in a box of four. Best of all they are beautiful to the eye, pleasing to the touch and a great way to reveal your table's natural grain. The innovative shape is a square with two subtly rounded corners to give it a modern twist.
