Slate Stone Coaster Set

Regular price $34.00 Free Shipping

Our minimal coasters do more than eliminate watermarks—they dry instantly! Created with diatomaceous earth, Dorai’s Slate Stone 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 Slate Coaster Set includes four coasters that pair perfectly with a beverage of your choice.

Cleaning Instructions: If your coaster gets stained it can be cleaned in two ways. For light stains or scuffs use a mild sanding tool or metal brush to gently rub off any marks. For more extreme stains, small amounts of hydrogen peroxide will do the trick.

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.

Thought I was being silly, but holy crap these are great

I definitely thought these were going to be one of those totally unnecessary purchases that I spent too much on and would justify it because of the eco-benefits. But holy geez these were so worth it. I had a glass tip over and the coaster dried up within a few seconds—they definitely live up to the description, if not out perform it. They look so much nicer than I thought they would too. Bring back the lighter color with the coral reef pics on them, I want more!!

Great in the bathroom

I gave it 4 stars only because the wave pattern on the stone hurt my feet when I use it without the cover. If you made it flat, without the indentations, it might not hurt as much.

As advertised

Very pleased with how these coasters look and function. No more coasters stuck to glasses due to sweat or overflow onto furniture from condensation.
