Work for any 1x4 calm strips you can find.

Calm Strips are textured, sensory stickers designed to help reduce stress and improve focus through tactile stimulation. They are reusable, residue-free, and can be stuck to various surfaces like phones, laptops, and desks. The texture of the strips, like Soft Sand or River Rock, provides a sensory input that can help regulate restless energy and improve concentration.

This makes a great silent fidget!
