This fun pendant is smooth on one side and has nubs on the other for a double sensory experience. A durable pendant great for those that have oral and tactile sensory needs. Length - 5.0cm, Width - 4.3cm at the widest point, Thickness - 0.8cm. Long cotton cord approx 85cm easily cut to a desired length. Looks more like a regular necklace than a chew tool. Soft but hard wearing.
