Stone Cold Custom Calls are made out of Solid Surface Countertop Materials, which provide a highly dense sound chamber for air to travel through. The result of using this material is a highly responsive call that is easy to blow and resilient to the elements. Solid Surface Countertop Materials are also incredibly unique in their appearance and feel that they deliver. There is not another call on the market that has the visual appeal that a Stone Cold Custom Call has, as Solid Surface materials are designed for a higher esthetic in our homes and restaurants. Without a doubt, you will be drawing the attention of all your hunting buddies with the newest addition to your lanyard. Just by holding a Stone Cold Call you can tell that it is built with durability and longevity in mind. This is why we choose Solid Surface materials when designing our calls. Every Call produced using this material is inimitably different in appearance than any other, meaning that there are no two calls that look exactly alike. This provides every Stone Cold customer a call that is uniquely theirs and theirs alone. Despite the variance in visual appearance, every call is produced with the same amount of care and attention to provide a synonymous sound and composition across the board.
