ORAL MOTOR TOOL: ARK therapy tools help build oral tone and improve a range of speech, feeding, and sensory skills. Perfect for home, therapy, or anywhere in between. KID-SAFE MATERIALS: Developed by a speech-language pathologist (SLP), ARK products are made in the USA with medical-grade materials. Great for speech therapy, feeding therapy, and more, they should be used by a therapist or trained adult with their client or child. MAKE DRINKING EASIER: The ARK Select-Flow Valve makes drinking easier by controlling the direction of fluid - fluid flows up into the straw, but does not empty back into the cup. Because fluid always stays at the top of the straw, less effort is required for each sip and less air is ingested. As a result, users tend to experience less coughing while consuming more fluids. DRINKING AID VALVE: The one-way flow valve is easy to take apart, clean, and put back together. Highly recommended for individuals with oral motor difficulties, a weak suck, or problems generating and maintaining suction. Just press the tapered end of the valve into the bottom of a straw and you're ready to drink. The Premium One-Way Valve is compatible with most regular drinking straws measuring .25" in diameter. Recommended for thin liquids (water, milk, juice without pulp, etc). Comes in a pack of 3.
