Regular coasters are perfect for preventing spills, drips, and condensation on flat surfaces, but these cool new Great Coasters are all-terrain coaster / cupholders designed to keep drinks stable on uneven surfaces like sandy beaches, grass, snow, carpeting, and more. Perfect for holding cans, bottles, cups, and snacks at the beach, picnics, backyard BBQs, poolside, and sporting events. They come in a set of six in multiple colors and are made in the USA, where we can never have enough cupholders indoors or out.
