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.

The best coster ever

When we have guest over it like our coasters are magic they work exactly as expected.

Best coasters EVER!

Living in a tropical environment, glasses of any iced beverage always leads to tons of condensation! Was fed up with every single coaster ever used in the past, that led to the same results....wasted money spent and extreme frustration as to unabsorbed condensation water dripping off the glass everywhere, all over furniture! Although hard to believe, up until reading an exciting review on these coasters from a friend and then trying some out myself, although skeptical, I was blasted with the amazing and unbelievable success in such a product!! THESE DORAI COASTERS LITERALLY WORK LIKE MAGIC!! Every drop of condensation is absorbed by this incredible invention of these coasters made out of diatomaceous earth! Now...NO condensation is dripping anywhere! 100% absorbed as advertised!! WOW! So enthusiastically sold on these, I purchased several more sets for gifts!! THANK YOU Dorai Home!....you guys ROCK!
