This is an accessory for the electric nasal aspirator Merci Pot S-502. I used it a few times, but it has been stored at home for about 5 years without use. The tube has yellowed slightly due to deterioration, but it is still usable. After use, it was washed, disinfected, and dried before storage. Regarding regulations: According to Mercari regulations, the main unit is a medical device, so the main unit cannot be sold. This is a sale of accessories only. Thank you for your understanding. Thank you for viewing. #BabySmile #MerciPot #ElectricNasalAspirator #Baby #BabyGoods ②
