Set of 6. The glass artists at Colorful Visions love this glass. They select portions of the glass to make into coasters, then hand cut and polish each one. Each coaster in the set is different from the next, you'll have your favorite we guarantee it! Measure appx 3 3/4" square. Polished edges to prevent cuts, who needs that! Cheers! Arrives in a white square gift box, with artist bio.
