Mandark 4PCS Car Cup Holder Coaster, Silicone Anti-Slip Vehicle Insert Water Bottle Mat, Automotive Interior Insulation Drink Cup Pad Decor Accessories, Universal for SUV, Sedan, Truck (Black)

So, these work wonderfully for their intended purpose of acting like a coaster in the bottom of your cup holder. Non-slide design. Cupped edges keep any condensation in the coaster. But they can be used for so much more. One of the things I used these for is under jar candles. Since the silicone is so soft and pliable, just take a pair of scissors and trim off the raised sides. Then you have a flat, non-skid surface to place under glass candle jars. This keeps them from sliding on wood furniture and keeps the heat away from the wood too. Or, just use these coasters as is on a table when you are doing crafts. The raised edges will keep in beads, buttons or anything else you are working with and won't slide. So many uses.
