Review on 🧼 Abrasive Bristle Brushes and Mandrels by BUYGOO by Solomon Inks

I thought it was the same piece of plastic disk in different colors. That's not true, these are different grains. If you use them on flat surfaces, they're probably great. They aren't as flexible as 3M drives and don't work as well in tight spaces. 3M 80-grit sanding penetrates tight corners and eliminates fluff from wood carvings. This brand's 80 grit erases every detail, and you could probably carve wood sculptures with it.
