From Matt Adkins at Glass Relief:
These coasters are inspired by my love of the natural aquatic world. The unique design formed to the surface of this turquoise aqua glass was inspired by the beach. You can see the water at the top using blue and turquoise, the foam in the middle and the sand at the bottom creating a close-up on the sea coming onto the beach. The top side smooth.
These coasters can be used for cups, warm or cold on any surface, it will stay in place thanks to the 4 bumpers on the underside of each coaster.
