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

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

Dimensions: 4” x 4” x 1/3"

  • Eco-friendly, non-toxic, and long-lasting materials. 
  • Dorai products are made from instant-drying Diomat (our sustainable combination of Diatomaceous Earth and recycled paper) that causes water to instantly dissipate.
  • Helps prevent bacteria growth, by eliminating the moist environment where mold thrives. 
  • Functional design created for the modern home.

Cleaning Instructions: In the case that 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, small amounts of bleach or hydrogen peroxide will do the trick.

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!

We love them

These are exactly what I was looking for. I use them by my sink to keep puddles of water from accumulating under my soap dispenser.

Diatomaceous Earth...what?!?

Who would have thought they could make a coaster out of diatomaceous earth? And it works! We tested them out with iced water and glasses dripping from humidity and the coasters were easily able to keep up with the drips. Also, they did not scratch our wood table. A hit all around! I would probably use a different coaster for red wine or something that would have the potential to stain but they are great for iced water.
