I recommend the Daiso eyebrow razor with a protective cap.

I recommend an eyebrow razor that I use well. It is a Daiso product.

This is a very affordable product, with a pack of 3 for just 1,000 won! I usually use the Kai eyebrow razor to trim small areas, but I use this one for larger areas or removing upper lip hair, and I am extremely satisfied! Since the razor is quite wide, it seems like an excellent product for shaving upper lip hair. I highly recommend it.
