2 3/4" X 16 1/2" PSA 無品牌 MIRKA GOLD 銼板片

The adhesive backing on these sheets grips the file board firmly without lifting, even when I really lean into the sanding passes. Paying about a third less than the usual price just because the packaging is plain? Fine by me.

I’ve been using these file board sheets on a few sanding projects, and the 2 3/4" width is just right for getting into tight spots without clogging up. They peel off cleanly from the backing and last noticeably longer than the cheaper rolls I’ve tried before.

I was pleasantly surprised how well these hold up on a long sanding session—the adhesive barely loses grip even after heavy use. For the price, getting the same gold film quality without the fancy packaging is a no-brainer.
