I don't know the size, but my child used it when they were 2 years old, but they disliked it and I barely used it even once. I decided to list it because I thought it was still cute and usable. This is a used item, so I will give it to someone who doesn't mind. Please refrain from purchasing if you are sensitive. [Cute Design] Baby mittens designed with Mickey Mouse's face.
