Tactile Mitts come in a set of 8 that each have different textures on them. This is a brilliant way to take a hands-on approach to proprioception.

You can massage those that need little more proprioceptive stimulation than others and the feel varies on how much muscle you use to massage. This is a great way of learning what textures make you feel better than others through tactile stimulation and also causes for a great bonding experience between the two users, whether it's a friend, sibling or parent.
