Diatomaceous Earth Coaster ，Set of 6，Unique White Absorbent Coasters for Drinks，Modern Aesthetic Instant Dry Stone Drink Coasters（Grey）

I love them! They won’t slip.I’ll be purchasing the darker ones for stainable drinks though.

They look cool, but stain easily. It does come with sandpaper to sand the stains, but it takes a lot sanding

Love them, but returned the white for the gray.

These really do seem to dissipate condensation almost instantly as advertised, though we live in the desert where the humidity is currently 11%. The white color is pretty sleek and modern in person, definitely has these ridges though as seen in attached photos. It does leave slight marks if you spill something other than water, like black/green tea or juice on it, but it's much much lighter than if you spill it on say the carpet or fabric. It doesn't seem to come off easily with rinsing, will have to look up other methods to clean the stone.They're super lightweight compared to other stone coasters we have, but don't seem to be too easy to break or fracture, and we've had no issue with chipping so far despite a chaotic household. They do stay put pretty well on the table when you use the little bumpers on the bottom, and even stays pretty well on slick surfaces like polished granite or marble. The drinks also hold on the top pretty well and don't get knocked/slid off the coasters easily like the marble coasters do, regardless of base of the drink holder (aluminum can, crystal, glass, silicone hydro boot).For the price and how convenient it is to dry almost immediately with minimal staining, I think it's a very fair price for a set of 6. I really like having these in my space where I spend long hours at a time, knowing they'll dry and won't leave any water pooled there to later make a mess.

I've been using porous ceramic coasters for decades because they are better at soaking up moisture than less porous material. But I still usually put a napkin over the coaster to help it out, and if I used the same coaster over the course of a week, the bottom always mildewed and had to be cleaned.Problems solved! I have diatomaceous earth bathmats, sink mats and houseplant saucers, but it still didn't occur to me that diatomaceous earth coasters were probably a thing. I saw these and was very excited. They didn't let me down. They are so very lightweight that at first I thought I must have been scammed. But I wiped each one with a wet rag, and the water quickly disappeared. Then I squirted water on them, with the same results. They work amazingly well, and I love the asymmetrical shape and the size in general.They also come with little rubber feet that you can stick on the bottom to keep the coaster elevated and less prone to slide, and a small round of sandpaper to quickly buff off any stains. I can honestly say that these are the best coasters I have ever used, and I plan to use them exclusively. Highly recommended.

We love them!! The only downside is they have ring stains from the drinks.

Not sure what these are made out of but definitely feels like stone! they have a smooth side and rough side. They also came with non slip rubber pads to be pasted under them. These are light weight and perfect for my wok desk. They are big enough to hold a standard mug and water bottles. They do keep spills somewhat controlled but I wouldn’t really 100% on that. Overall, very nice perfect for any environment.

There are horrible as a coaster. They do not get clean and they Stain immediately.
