Self sealing cup caps that stretch to fit missing cups or glasses prevent spills when they are shaken or knocked. Simply place the cup cap over a cup or glass, insert a straw through the purpose made, self sealing eyelet in the centre and you have a virtually spillproof container for liquids. Made from Tenuras new antimicrobial silicone, the cupcaps are strong, washable and have excellent grip qualities, meaning they can be used many times over. Tenura antimicrobial cupcaps are perfect for children and people with an unsteady grip, protecting furniture, carpets and clothing from spills. The cap will also keep drinks fresher for longer and can also be used to store the drink in a fridge.
