bökee is the first and only bottle prep and sippy cup accessory that enables parents and caregivers to open, fill, 100 close a bottle or cup with just one hand! The bökee is made of 100% food-grade silicone and dishwasher safe. It's compatible with all standard and wide mouth bottles; glass, plastic, and silicone! bökee also keeps breast milk from spilling; it keeps silicone pumps from tipping over, and bottles upright when transferring from bag to bottle (no more accidental knock-overs!). Medicine bottles and stubborn jars can also be opened one-handed with bökee. It was created for parents, by parents, to make one step of your daily feeding journey a bit easier!
