About this item

• Cup Sleeve Size: The SIKAI CASE portable silicone cup sleeve is suitable for glass bottles, children's cups, coffee cups, etc., with a size between 2.8"-3.8". Please refer to the size chart for reference before purchasing to ensure the cup sleeve fits your cup.
• Versatile Silicone Cup Sleeve: SIKAI CASE reusable silicone sleeves are made of BPA-free, food-grade, durable silicone. Premium silicone material can make the water bottle and quilt fit tightly, and the surface is very soft and non-slip, which can prevent the bottle from loosening and help you hold the slippery water bottle comfortably and firmly.
• Functional and Fashionable: SIKAI CASE portable coffee cup sleeves feature adorable shoe charms and straw holders around the sleeve, allowing you to personalize your tumbler or bottle to your liking. The variety of colors adds a fun and festive touch, perfect for Halloween. They look elegant and eye-catching. A great gift for anyone who loves to accessorize their cups.
• Customize Your Cup: Our set includes 2 silicone sleeves and 2 colorful lanyards, allowing you to mix and match to create a unique look for your water bottle. This stylish and simple design is perfect for both indoor and outdoor use, such as the office, home, gym, camping, swimming, driving, fishing, and more.
• Easy to Install and Clean: Simply wet your tumbler and the silicone cup sleeve, then slide the tumbler into the sleeve. For the silicone lanyard, refer to the image for the knotting method to prevent it from slipping off. Cleaning is a breeze - just rinse with water or use a soft brush/damp cloth, and then towel dry or air dry. It's so easy, even kids and seniors can do it!
