I use my coasters for my kitchen sink to simply hold my sponge. I'm a bit of a neat freak and don't like clutter. These are so simple and minimalistic. They are big enough that any sink sponge will fit on this. They definitely get dirty over time but for the money you pay, just get a new set. Seen in pics below, I actually did a light acrylic paint on mine to clean them up after well over a year of use. Mine get wet but not sopping wet because it's only a wrung out sponge sits on it. I know AI Rufus said you can't paint them but after I did, they are looking like new again. If they fail at some point, i will simply repurchase. Read more




These water-absorbent diatomite coasters are surprisingly impressive. They’re extremely lightweight and do an amazing job at soaking up moisture almost instantly—no more puddles or rings left behind. The rectangular shape gives plenty of coverage, and they look sleek and modern wherever placed. One thing to note: because they’re so light and have that stone-like feel, they do seem a bit fragile. I get the sense that if they were dropped on a hard floor, they might crack or break. As long as you handle them gently, though, they work beautifully. Overall, they're stylish, functional, and great for keeping surfaces dry—just don’t toss them around! Read more


I really love this product. It's been a game-changer in helping to protect my white bathroom counters. The tray absorbs well, and looks very clean/nice. With that said, it definitely discolors over time. This photo is comparing the first one I used next to the brand new second tray that came in my order. The one on the left was used for 6 months. As you can see, its dingy/yellow. I followed the directions and used the sandpaper that came with it. Sanding/cleaning it removed a few water stains, but didn't help the discoloration. All in all, I am happy with this product, though. Price is fair. I will likely just buy some back-up ones for when this second one discolors. Read more

These are nice. They keep my from having to constantly wipe my sink area all of the time. They absorb water amazingly. Read more
These work great and a lot nicer on the counter than a folded dish towel. I have recommended to several people after trying them myself. The water drops disappear within minutes. If any dark spots appear from drips they can easily be sanded out with a little fine sandpaper or emery board Read more
This dish does help keep water off your counter tops. It absorbs and dries quickly. The problem is the little rubber feet are just stuck on there so when you go to wash the stone (it was starting to grow a bit of mold so it needed a bleaching) the feet will fall off and won’t stick back on. I hot glued them back on but I wish the feet were part of the stone itself and not small rubber pieces. Read more
I really like the absorbent coasters. I placed one on my window seal and one in my bathroom. They look classy and blend in well all keeping the area clean and fresh looking. I bought a second one in the dark color to match my kitchen counter. Love it as well for the dish and hand soups. Read more
