These silicone coasters come in a set with other colors. Kelli and all her friends always comment that they are "so cute". I'm certain they are very popular and Target must be selling tons of them. Why am I posting this photo??
As you can see, they aren't very functional. They may be cute, but the moisture either on the coaster of from the condensate of the cold drink on the coaster is not retained on the top surface of these coasters. The result is moisture dripping off the coaster and leeching under the silicone coaster. This results in moisture being retained between the coaster and the counter or table top surface. If you are using these on wood finishes, it will leave marks such as these where the coaster was. It's quite disturbing and makes the coaster non-functional. Of course if it was on a glass, Corian, granite, formica, stainless steel or some other solid surface material that is easy to wipe away water stains, just wipe it off. If it's used on a more delicate surface like this wood dining table, you can only hope it will wipe away and not leave a permanent mark.
Luckily there are no permanent markings left... yet! Since these are soooo cute, perhaps they should remain on our table tops for decorative purposes only!
