NEW! Wonderfully soothing 8" sensory tubes that contain 2 colors that bubble and mix when you shake, turn, or invert them... then watch as they slowly separate back to their original 2 colors! Color Mixing Tubes provide a fun and silent way to relieve stress, decrease anxiety, take a short re-focusing / re-set break, and help calm active bodies and/or busy minds. These calming sensory tools feature a durable, leakproof, very easy-to-grip design. The perfect visual sensory tool choice for car rides, quiet spaces, indoor recess, mindless play while watching tv, and calming corners. A fabulous 2-handed bilateral coordination toy. Sold in single tubes (we'll surprise you with what color) or in 3-pack assortments that feature 3 assorted fabulously colored tubes. Designed for ages 3 to adults. Big thumbs up!
