Thank you for viewing. This is a dental care toothbrush with soft bristles that gently care for teeth. I was recommended this toothbrush at a dog teeth brushing seminar and have been using it. I purchased it online because the one I was using became old, but I accidentally bought the wrong size, so this one is new, unused, and unopened. Since it's a different size than the one I usually use, I hope someone can use it. The brush is so soft that it doesn't hurt even when rubbed against human skin, so I think it won't hurt your dog's gums either. Although it is a new, unused item, it has been in someone's possession once, so please understand this before making a purchase. I am also selling various other items as I clean up my room, so please take a look if you have time. # AWAYUKI # Awayuki # Dental care toothbrush # Small # Made in Japan
