Ecopiggy is excited to launch the ecoteether, a 100% natural rubber teething toy designed by calmies. Calmies is an all-natural rubber infant teething toy. Safe, soothing, sustainable, and multi-sensory. The easy-to-grasp ball shape is a functional toy and developed by a doctor to provide relief while teething. Ecopiggy’s natural rubber teething toy is easy for infants to grasp and helps with sensory motor skills.
