I've been using 3 M sticon for 20 years, but this gold is the worst product. Since abrasive ability falls off in a blink of an eye, it is different from the previous product. When selling such a product, Monotaro's reputation will fall. I will never buy a 3 M sticon. Finally I finished using it, but I wasted product costs and working time.
I feel that the product is bad as I think that it is totally different from the manufacturer's model change. It is a state that you have to exchange paper frequently. We have been using 3M for a long time, but we are considering whether to use the manufacturer instead.
