Terms of Service: ※ According to Mercari's regulations, the main unit is a medical device and cannot be sold. Only the accessories are for sale. Thank you for your understanding. I was able to blow my nose immediately after purchasing, so I only used it a few times. I only used one of the two nasal nozzles, so the other one is new. The cleaning brush has also not been used. All accessories are included. It's ready to use immediately.
