These teethers contain purified water and can be chilled in the refrigerator to provide a cooling effect that helps alleviate teething discomfort. The cold surface offers relief for sore gums. The circular design is lightweight and sized for small hands, making it easy for babies to grip and maneuver for self-soothing. Each teether features textured surfaces with rounded bumps and ridges to gently massage gums while supporting oral development. The set includes three teethers, allowing caregivers to rotate them between use and refrigeration. They can be cleaned with warm, soapy water and are built for regular use.
