This Tockrop sanding sponge set is a must-have for DIYers, woodworkers, car enthusiasts, and crafters! You get 15 pieces total: 3 each of 5 grits (P400, P600, P1000, P2000, P3000), so you can go from rough shaping to fine polishing all in one kit. Each sponge is 4.5 x 5.5 inches—a handy size you can even trim if needed. The flexible foam design makes it easy to sand curves, corners, and contours without hassle. Use them wet or dry on wood, metal, plastic, drywall, automotive bodies, marine work, and more. The red velvet back is comfy to hold, and the grit is printed on so you won't mix them up. Perfect for model making, furniture repair, stone polishing, or general home projects. A versatile, professional-grade set that makes sanding way easier!
