I bought this for my child, but I have some extras, so I'm selling them(^^) They're colorful and easy to grip, so my child was immediately interested, and they were helpful when starting to brush their teeth★ Great for trying out too★ Excerpt from the HP description below: ◆Unique design that combines a teether ring and a toothbrush◆ Jordan was founded in Norway and is a leading Nordic oral care manufacturer loved in 50 countries around the world. They have a wide variety of products for infants to adults, with high quality standards and attractive designs. 【Step 1/0-2 years old, soft】 It's important to establish a habit of brushing teeth from infancy. The design, which integrates a teether ring and a brush, allows children to get used to brushing their teeth naturally while chewing. The rounded part at the bottom has rubber that acts as a teether or pacifier. Also, the short neck is designed to prevent the child from gagging. The brush shape with a recessed center is designed to fit baby teeth, and the soft bristles gently brush the child's mouth. Since children often miss spots when brushing on their own, please brush their teeth for them as a finishing touch. <Product Information> ■Soft bristles ■Brush shape with a recessed center fits baby teeth ■Toothpaste amount indicator ■Short neck (prevents gagging) ■Easy-to-grip circular design ■Teether and pacifier with bumps on the handle ■Available in 4 types (4 colors) ■High-functionality ■Colorful and cute design makes brushing time fun ■Feels like a toy
