Red Inks are the brothers of the Ink Blacks, the well loved linear switch in community. Smooth from stock due to the custom housing material and coated spring but especially smooth with a great sound after lubing.
Note. The first version of Gateron Red Ink switches had minor issues with the leafs being loose and prone to falling out when dismantled. As of November 2019 that issue has been resolved.
Gateron Ink Black respond particularly well to being lubricated. Krytox 205 Grade 0 is a great choice for an extra smooth feeling switch.
