Review on Effortlessly Achieve Smooth Sanding with KALIM 132Pcs Sanding Sleeves Mandrels: The Ultimate Sanding Solution! by Carlos Phillips

They work well but they seem to wear out quickly from the sanding drum causing them to slip out of the rubber mount. I had a lot of it to do. Yes, they did the job, but it took a lot longer because I had to keep putting new ones on. The beats themselves (metal stand with rubber drum) are great. If you get these, they are definitely worth it. I would only recommend buying different sanding rollers.
