Sterilized cotton balls Purchased for the treatment of a child's umbilical hernia. I changed them several times and now it's completely healed, which is a relief. I have some left over, so I'd like to give them away to someone who needs them. I will send them via Takkyubin Compact. - Brand: Osaki - Product Name: Neo Pearl - Contents: 20 pieces - Purpose: Sterilized cotton balls - Size: 20-3 Thank you for looking.
