Wrap it up… Our products are different, which means you can stand out from the crowd when you chill with us. Our silicone tumbler sleeves add a unique touch to any 20 or 30 oz tumbler. Simply slide one onto your favorite tumbler and it will make it easier to grip and help protect it from scratches and dents. The silicone sleeve also keeps the exterior of the tumbler from getting hot when exposed to Sun for long periods of time and also keeps it from scratching the gelcoat on your boat. The tumbler wraps are also non-toxic and plastic-free for years of enjoyment. Patent pending.
