$2.00 T2201 This is the original sensory brush. The bristles of this small rectangular plastic surgical scrub brush feel soft if used in one direction but stiff and coarse if used in other direction. The bristle tips are specially cut to create a three sided point so more surface area of the brush makes contact with the skin. Try it for tactile defensive programs, sensory stim, or just to wash hands and fingernails. (Approximately 2" by 3").
