Two spare silicone o-rings - especially for the matte lid B.Box sippy cup.
To insert the o-ring, hold the o-ring with one finger on the rim of the lid to keep it in place. Use another finger to run alongside the o-ring around the rim. Be careful not to push too hard with sharp objects, such as nails, as they may tear the o-ring. Repeat step 2 twice to ensure the o-ring is tightly in place. Screw in your base and your cup is leakproof and ready to use!
Dishwasher safe. Made from silicone. BPA, Phthalates, and PVC free.
