Acrylic coasters with suspended glitter to look like sand floating around in a tidepool! Glitter is floating in liquid so it moves around when you turn the coasters. All coasters come with a blue rubber bumper that makes them non-slip around the circumference of the coaster but if you like the look of just the coasters, it is removable!
