Tombow Mono Tough Eraser

Tombow Mono Tough Eraser. Released in November, 2019, Mono tough is an eraser developed to be flexible but resistant to breaking. Even though Mono Tough is made with the same material as other Mono eraser, Mono Tough is about 8 times stronger than the regular Mono eraser. The eraser sleeve is also designed to accommodate this strong eraser — the top of the sleeve is cut slanted to disperse the bending force, and the sleeve is perforated to make sure the the last bit of the eraser is not left unused.
