The 305 grams hand roller is one of the heavier versions in the kaiko range of hand rollers. It functions as both a weighted product and fidget. It is our most recommended weight for teens and adults clinically (unless there is hand function issues for example).
These are beautifully weighted and smooth. It comes in a zip-up black case for great storage. Amazing for those that need to constantly keep hands busy & to assist with agitation and anxiety.
