Merci Pot S-503 Electric Nasal Aspirator Accessories Used about 4 times. After each use, all parts were disassembled, washed with neutral detergent, soaked in disinfectant, and stored. Only the tube part is made of silicone, so there is slight discoloration due to aging, but there is no problem with use. One unused nozzle is included. All parts will be packed in the box and shipped. *According to Mercari regulations, this is a medical device, so the main unit cannot be sold. Only the accessories are for sale. Thank you for your understanding. Parenting goods
