This is a set of 4 silicone toothbrushes for children (approximately 2-6 years old). These toothbrushes are designed to allow children to brush their teeth simply by holding them in their mouth and moving them side to side. (They are designed for both upper and lower teeth, so just biting down is enough!) Made of silicone, they are soft and gentle on the gums, allowing children to enjoy brushing their teeth independently!! This product is currently very popular with mothers♪ Available colors are blue and pink. If you have a preference, please let us know in the comments when you purchase. (If there are no comments, we will ship two of each color, blue and pink.) We still have stock, so if you would like to purchase more than 4, please comment. We will offer a discount for multiple purchases. Thank you.
