Our patented design allows condensation to drip into the Barnacle where it becomes trapped. Just remember to empty the contents between each refill. You’ll be surprised by how much condensation ends up in there! Better there than on your table, homework, or clothes.
One size fits most standard size cups, bottles and cans (optimized for iced coffee cups). Never stress about searching for a coaster again - the barnacle is attached and goes where your drink goes.
Did you know most cardboard coasters are used only ONE TIME before they end up in a landfill or headed straight for our oceans? Barnacle Coasters are made of durable silicone rubber so you can use them again and again. Dishwasher safe, too!
