Our minimal coasters do more than eliminate watermarks—they dry instantly! Created with diatomaceous earth, Dorai’s River Rock Coasters are both sustainable and designed to rapidly remove moisture.

Each cup coaster is a different shape and pattern, emulating the unique, natural qualities of stones. The River Rock Coaster Set includes four coasters that pair perfectly with a beverage of your choice.

Dimensions: 4” x 4” x 1/3"

  • Made with eco-friendly, non-toxic, and long-lasting materials.
  • Dries instantly thanks to Diomat®, our sustainable combination of diatomaceous earth and recycled paper.
  • Helps prevent bacteria growth by eliminating the moist environment where mold thrives.
  • Functional design created for the modern home.

Cleaning Instructions: If your stone gets stained, it can be cleaned in two ways. For light stains or scuffs use the included sanding tool to gently rub off any marks. For more extreme stains, use a small amount of hydrogen peroxide or bleach to treat the area.

These are simple but very well made, and the graphics help make a lovely home feeling. Big upgrade from the cheap 1/4 inch coasters I had before!

Dish Rack with accessories

Bought the dish rack with accessories and overall am pleased with the product. It functions as advertised and has a modern look.
The utensil holder design though allows for smaller cutlery to fall through the sides and front slats, sometimes onto the floor or to get stuck at the bottom making it difficult to remove. I think there could be some improvements made with this.
I also bought a set of coasters. They are great. No more water marks on furniture. Highly recommend these. Can’t imagine buying any other type of coasters after using them.
