Ultra Durable Sanding Sponge 2.0 uses a new generation of polyester materials, provided with brand authorization from the base material manufacturer, ensuring the performance and stability of each batch. The new generation sponge sandpaper comes in a drawer-style packaging design, with different grit sizes distinguished by sponge material color and the grit number printed on the surface. This design significantly optimizes user convenience. We have gathered feedback from many experienced users and decided to offer three available thickness options: 3mm, 5mm, and 10mm.

Specification
3mm thickness is suitable for most irregular surface sanding tasks in everyday use
5mm thickness is especially suitable for sanding small curved surfaces
10mm thickness provides excellent support, making it ideal for sanding large curved surfaces.

Additionally, the new materials greatly enhance the durability of the sponge sandpaper. Simple cleaning with a brush or washing with water can almost fully restore its cutting performance.
