Our pack of P and Q offers two oral exercisers for practicing biting and chewing skills! Safe, non-toxic durable surface for biting and chewing activities. In addition, they are lead free and latex free, and do not contain PVC or phthalates. P and Q are solid rather than tubular and offer a firmer surface for biting than the red or yellow Chewy Tubes. Young children enjoy grasping the P with their newly developing fine motor skills. The bitable stem of the P reaches back into the molar area providing valuable proprioceptive input. Measure 3″ L (7.6cm) and 1/2″ (1.3cm) diameter.
