This is a finger toothbrush. I bought two, one for each of my two pets, but when my husband tried one on, he said his finger was too big and it hurt... So, we didn't end up using them. The brush part is about 1 cm long. It can be hung up to dry, so you can keep it clean. I think they cost around 500 yen each. I'll send the pink one in a Ziploc bag. Thank you.
