Merci Pot S-504 I tried using it once, but my child didn't like it, so I'm selling it. (It hasn't touched the nose) Everything has been sterilized. There are water droplet marks from when water was run through the hose, so please purchase only if you understand this. ※ According to Mercari's regulations, the main unit is a medical device, so the main unit cannot be sold. Only the accessories are for sale. Thank you for your understanding. (This is stated in accordance with the regulations) Instant purchase is welcome.
