To protect your ShakeSphere tumbler more effectively and make it easier for you to carry it with you, we have introduced the ShakeSphere tumbler sleeve.
 The cup cover is made of carefully selected neoprene material, which is mainly used in diving suits or various sports protective gear. High-quality neoprene material is more effective in enhancing protection and can also keep the temperature in the cup longer.
 The cup holder is equipped with a carrying buckle, which can easily hang the hand-cup anywhere. You don’t have to worry about having no place to put the cup even if you carry more things in your hands!
 This product is made of 100% high-quality neoprene.
