Norco Rainbow Exercuse Putty is a therapy device that can be used for everything from enhancing motor skills to increasing hand strength and is made to be a fun and engaging activity. The bright, bold colors can encourage children to participate and comply throughout their therapy sessions. Each color indicates a different resistance level, making it easy to visually differentiate between levels and provide a clear manner of tracking progress; these varied resistance levels also offer a graduated path for recovering, developing, or strengthening.
