ARK's Cip-Kup makes drinking easier for beginners and individuals with oral motor difficulties - its unique one-way valve keeps fluid at the top of the straw so users don't need to generate or maintain suction, reducing effort, minimising air ingestion, and decreasing coughing and choking while consuming more fluids. Also a great alternative to sippy cups, promoting proper lip and tongue positioning and helping transition babies straight from bottle to straw. What's Included 1 flexible squeeze bottle with twist-on cap (8 fl oz, ~2.5" x 2.5" x 5") 12 Glad flex straws 8" of polytubing (reusable, chewable, durable straw alternative) 1 select-flow valve (can be trimmed to increase flow and further reduce effort) 1 x ¾" Lip Blok (discourages biting on the straw or inserting it too far) Sturdy storage box with instructions How It Works Squeeze the bottle until fluid reaches the top of the straw, then release. The one-way valve holds fluid at the top of the straw, so the user only needs minimal effort to drink. Less air is ingested, reducing coughing and choking.
