Mary Square Cup Sleeve

This sleeve is designed primarily for standard disposable coffee cups and iced coffee cups. While the neoprene material offers some flexibility, it is best suited for cups with a tapered, standard shape rather than wide-bottomed tumblers.

The neoprene material acts as a thermal barrier, which helps maintain your beverage's temperature for longer than a bare cup. While it won't replace a vacuum-insulated thermos, it significantly slows down heat transfer and prevents condensation from forming on the outside of your cup.

While the sleeve is durable, we recommend hand washing it with mild soap and warm water to preserve the shape and elasticity of the neoprene. Simply air dry it afterward, and it will be ready for your next drink.

Not at all. The neoprene is lightweight and slim, adding minimal thickness to your cup. Its collapsible design means you can easily fold it flat to tuck into a pocket or bag when not in use.

Yes, the neoprene effectively absorbs condensation, keeping your hands dry and preventing water rings on your desk or car console. It provides a much more comfortable grip than a wet, slippery plastic cup.
