Super easy to use Kobayashi Liquid Band-Aid ✨ A must-have product in our home all year round It is really more practical than the ordinary paper sheet-like hemostatic stickers because it has its own waterproof function, it is very clean and hygienic, and bacteria and air are not easy to enter the wound and get infected. It's a bit like applying nail polish 💅🏻 When you open the lid, you will have a strong potion smell Comes with a brush on the lid apply a thin layer to the wound Waiting quietly for it to air dry After it dries you will notice a thin film forming on the wound It can last at least 2-3 days and is absolutely waterproof Washing hands, bathing, etc. will not touch the wound and will not feel pain But at the time of the first application, when the potion entered the wound, it was a bit tingling for a while, depending on how bad your wound was. Anyway, when I first started to apply it, I really had to be brave enough to apply it 😂 Because sometimes it really hurts..
