Transformer Sensory SackNow every child can have their own transformer! Simply slip into the Transformer Sensory Sack and feel the mood change from sad to happy, from distracted to focused, from hyper to calm. The secret lies in the deep pressure and resistance from the heavy work of stretching, crawling, moving, rolling and snuggling in the Lycra sack. Use before or after school, and during breaks. Folds for easy travel. Not for use during sleeping. One size fits all
