Highly tactile, soft and pliable, Wikki Stix can be used by small fingers for all kinds of fine motor skills, to reinforce pre-writing skills, and for creative play. Wikki Stix are made of a strand of acrylic, hand-knitting yarn enhanced with a microcrystalline, food-grade, non-toxic wax and will stick to each other and almost any smooth surface with just fingertip pressure. They will not pull apart, but cut easily with scissors. Clean and easy to use...no preparation, no mess! Clean up is just a quick wipe with a dry cloth or paper towel.
