Color Slate

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 in x 4 in x 1/3 in

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. We recommend doing the sanding in a well ventilated area. For more extreme stains, use a small amount of hydrogen peroxide or bleach to treat the area.

Nice shape, great function!

These coaster have proved themselves immediately. I always have a glass of ice water at my disposal and it would sweat my former coasters into a puddly mess. These coasters are fabulous!

Coasters are awesome!

You will never have a drink ring again! And, they are so good at absorbing the moisture, the glasses don’t stick to the coasters when they sweat! Thanks again Dorai!

Best products

I’ve made several purchases and have never been disappointed. The fosters and sink and bath stones were gifts. I’m still hearing about how they love everything.


I ordered the coaster set and received the sink caddy. No worries, I like it. Don't know if there is a price difference.

We are sorry to hear that you received the incorrect product. One of our customer support agents will reach out to help further.

Great solution for drippy drinks

We love our Dorai coasters! It solves that annoying drip problem when the ice melts in a cold drink and gets condensation all over the surface around other coasters.
