Mionix Propus 380 is the physical answer to performance, design and innovation. The developed surface is treated with a special silver-metallic plastic coating. According to test results, this special coating offers optimal tracking conditions and improves the overall performance of the mouse movements. A thin base made of PVC-plastic has been implemented to give the stability from a hard mousepad without compromising the flexibility from a soft mousepad. The backside is made of natural rubber to ensure a steady grip.
