The Stunning Kaiko Spikey Hand Roller is the lightest in the range, so that the tactile input is the 'hero' when using. It provides both endless stimmy rolling and high input. Also a tool for safe 'ouch' when squeezed. Amazing for those that need to constantly keep hands busy & to assist with agitation and anxiety. May be a useful tool for harm reduction, tactile input and sensory desensitisation.
Rotate in your hand, roll between your palms, squeeze or roll to massage are four great ways you can use them. To gain an idea of how they feel to use - if you have some fat textas on hand place two in the same hand, side by side, and rotate around themselves.
