This is the 2nd generation of the Sword series. The case is made from CNC all-aluminum and has a four-stage color separation design that allows you to see the difference in colors from multiple angles. The case also has a detachable magnetic top that can be easily removed and exchanged for other colorful tops available for purchase separately. Additional colors will also be added in the future. The Sword series are the only keyboards on the market with a metal case that have the Varmilo EC switches.
