Each kit contains parts for one hand.
To use with both hands, please purchase a two-handed set containing two sets.

The stainless plate plate is separated on the left and right due to the difference in the insulation seal.

In addition to this, a key switch and a keycap are required for assembly.
In addition, a TRRS cable for left and right connection and a USB cable for connecting to a PC are required separately.

There are the following variations.

Backlit model

It has a backlit full-color LED that illuminates the switch. You can make a colorful keyboard by combining a switch that supports transparency and a keycap.
A temperature-controlled soldering iron is required for mounting. Also, please note that the implementation difficulty is relatively high.

Underglow model

Comes with a full-color serial LED tape for Underglow that shines cool under the keyboard.
