Comments on BSUN | HC Studio Roselle switches
The Roselle switches are a truly innovative switch manufactured by BSUN. One of the most obvious reasons is that it's stem is made from Y3, which is a brand new material. Due to the new Y3 material being used, the original molds and factory lubing technique BSUN had could not be applied to the Roselle switches. This led BSUN to create new molds and factory lubing techniques, specifically designed for this switch – SerpentKeys.
