Review on Nitrile Rubber Sheets For Plumbing, DIY, And Flooring - Pack Of 3, 6X6-Inch By 1/16-Inch Thickness by Jemar Lorenzo

I'm not using these for traditional repair jobs. I'm using them as almost perfect coasters. Why? 1. They are waterproof and protect tables. 2. They are thin so guests don't end up spilling the drink when they land off-center on the coaster. 3. Mostly heatsafe so they can handle hot mugs of coffee. 4. They can be washed. 5. Their rubber material does not scratch surfaces 6. They are cheap but still look high-end.Downsides? They are not really dishwasher safe. They will warp if you put them in the dishwasher. They are a little big for my needs but easy to trim. they could come in better colors like bright white or grey.
