Oral care sponge, Sakura type [30 pieces]. I received these from a children's hospital, but only the sponges were given to me, so I don't know the manufacturer. I also don't know when they were purchased. Please check the size in the photos. I'm selling these because I can't use them all. I have checked the bags for tears and stains, but there is a possibility I may have missed something. There are no instructions on how to use them, so please purchase them if you know how to use them. Please refrain from purchasing if you are nervous or seeking perfection. I will ship them in a Nekoposu box. Please note that I will have to pack them in a slightly compressed manner. If you understand everything, you can buy it immediately.
