Baby, Kids' and Children's Products Design Halooobaby 3 Stage Chewing Toy by Shenzhen Hailebao Intelligent Technology Co., Ltd. Halooobaby 3 Stage is a teether toy set made for the oral development of infants. The set uses a tiered hardness system of Shore A 30, 40 and 50 silicone. The round soft piece soothes and is easy to grip, the square piece massages emerging teeth, and the triangular piece reaches the molars. Surface grooves, small dense bumps and large dots give different massage sensations. Each colored core is fully encased in highly transparent liquid silicone, which prevents pigment leakage and supports safe chewing. Boiling, steaming and ultraviolet sterilization can be used.
