Store our granite coaster set in your freezer and carry the caddy to your celebration for a naturally chilled round of beer or soda. Handmade from reclaimed granite, the substantial anti-tip coasters employ the chillable quality of stone to keep your beverage cans cold and securely upright. The 1" deep hole precisely bored into each Coaster allows cans to nestle inside and stay cool thanks to the granite''s high thermal mass and aluminum''s high thermal conductivity. They combine to conduct heat from the can and keep your drink cool like no other coaster can. Keep your beverage cool by chilling the entire coaster set in your freezer for at least 30 minutes, or store them in the freezer so they''re always ready for action. Each Coaster is a different variety of granite, so sippers can easily identify their drinks. The hardwood and aluminum caddy keeps the coasters securely housed and the hand-picked beach stone handle makes the entire set easy to tote.Granite and stone color will vary and may not be as shown.
