1 quantity refers to 10 switches. BSUN Aniya R2 is one of the smoothest stock switches out there in stock form due partially to the materials, combined with the excellent factory lubing.  The switch uses POM housing and LY stem. POM material is widely used in industry for its seemingly "self-lubricating" properties, this is due to its low coefficient of friction (how "slippery" it feels) of 0.2, compared to others like polycarbonate at 0.3. This results in a very smooth feel with less "scratchiness". LY is a hybrid material with a low coefficient of friction of 0.2 or lower. Just like the special sound that can be brought by the switch of POM material, the LY material can bring a very unique satisfying sound. We are providing personal hand lubing service, done personally by our slick inhouse Lume Lubing expert.
