This is nasal tape designed to widen your nostrils and support breathing. I used one strip, but it didn't work for me. I bought it for around 800 yen for a pack of 8, and there are 7 strips remaining. The box is slightly torn, but if anyone wants to try it, please consider it. - Product Name: Breathe Right Extra - Type: Nasal Dilator Strips - Quantity: 7 strips - Strength: 50% stronger - Size: Regular Thank you.
