SipSnap is a universal silicone drinking lid that stretches to fit over any cup. There are two versions: SipSnap TOT incorporates a chew-resistant spout to create a spill-proof sippy cup, while SipSnap KID accommodates any straw to provide a splash-proof option for older children and adults. Offering control over cup materials as well as the flexibility to use what is at hand, SipSnaps can be transported in their case for use on the go.
