The fun never ends with these snapping, popping toobs! Each toob flexes back and forth, expanding from 8" to 30" and can be stretched, bent, and connected together. This is a great toy for working on joint-attention, reciprocity, response to sounds, and working on action words, such as "push," "pull," "pop," and "open." The pop toobs provide tactile stimulation while developing fine motor skills and auditory feedback. Most of all, these pop toob fidgets are just plain fun to play with! Colors vary.
