・I lost one and bought another, but then I found the one I was originally using, so I'm selling the unopened one. ・Isn't it difficult when babies and children who can't blow their noses have stuffy or runny noses? Personally, it was very easy to use and a very useful product. I would be happy if someone could use it. Manual pump with vacuum for powerful suction without using electricity. You can quickly suck out the snot even when the baby is sleeping. It's a portable size, so you can take it anywhere. There is no electric sound, so babies are less likely to be scared and it's easy to use. Can be used from 0 years old to adults. Quiet and can quickly suck up unpleasant snot, making it easy to use even at night.
