Customer review

Actual customer review

Description. Lorem ipsum dolor sit amet, consetetur sadipscing elitr, sed diam nonumy eirmod tempor invidunt ut labore et

“I was worried about whether it would work or not fall out of my nose because of the heavy weight while I ordered it, but when I received it yesterday and used it, I think it is lighter and has better performance than I expected. I have rhinitis and my nose is itchy and dry, but when I use it, I breathe through my nose!!!

People without rhinitis can take it for granted, but people with rhinitis have a hard time breathing through their nose.”
