Review on 📦 Tulead 320 400 Sandpaper Polishing Sheets by Bryan Fields

When I received them, I found that these sponges have 2 sides with a grit of 320 and 2 with a grit of 400. There is no visual indication of which side is 320 and which is 400. You can tell it by touch, but feeling the sponge every time you pick it up is just plain stupid. I used sharpie to mark the ends showing which sides are which. However, I would prefer that all sponges are the same grit and have what that grit is printed on it.
