Originally, I was in a bulking phase, so this is 4 out of 5 brushes. I will not send the box, only the contents. The guidebook will be included. Each brush is individually wrapped and comes with a cover, so you can rest assured. I bought this thinking it would work, but in the end, I can only use my fingers with my dog, so I'm selling the remaining brushes after using only one. The brush bristles are ultra-fine, soft, and have a flexible elasticity. You can brush without worrying about damaging your gums. The handle is also easy to grip and has silicone to prevent slipping. Please refer to the 8th image for the size. The bristles are about 1cm long. It says it's for dogs 5kg~, but I think it's more suitable for medium-sized dogs. My dog weighs 13.5kg. The size was just right. I purchased it for about 1,500 yen. Will be shipped via Yu-Packet Post Mini. #dogtoothbrush #dogsofttoothbrush #doggingletoothbrushorgums #dogfinebristledtoothbrush
