SK21 Numpad

Packaging for the SK21 numpad drops all pretext and goes all in with the Skyloong branding, including a blue box that matches the mascot. Speaking of which, it shows up in three different forms, and the relevant information once again is on a sticker on the side that confirms the SK21 is inside. A double flap and two side flaps need to be handled before opening the box, which reveals the numpad inside a plastic wrap similar to the SK61. Another manual is included here, but it belongs to the twin GK21 mechanical switch version that is a wired/wireless unit as opposed to this less expensive, wired-only optical SK21. A compartment on the side houses the other accessories, which are exactly the same as with the SK61: a USB cable, keycap puller, and switch remover.


The SK21 is so new that there is not much information on it out there, and the use of the GK21 manual confirms that some more updates are needed. Add to that the keycap color scheme, which has no mention of the Red Wine theme but clearly is one such implementation. The red keycaps are brighter than I thought they would be, so I wonder if there is going to be a mismatch in color with the SK61. Functionally, it is a complete numpad with four extra switches for F1–F4 up top, and four extra secondary functions tied to those, which can help when paired to a 60/65 % keyboard without the Fn key row. The side profile shows a black ABS plastic case which is relatively high in profile, and we will see on the next page if the SK61 uses the same approach.


A sticker on the back still says this is a GK21, which doesn't seem right. So clearly Skyloong/Epomaker re-used the same case as for the GK21 but swapped out the PCB for an optical switch version. This means the serial number and certification information is no longer applicable, and Epomaker says it is working on getting the newer SK21 labels, packaging, and manual ready to go out the door. There are two circular rubber pads at the top and two oval ones at the bottom, which is in line with the trapezoidal shape employed here. These will help keep the numpad in place on your desk, and there are no additional feet for elevation beyond what is offered by the high-profile case itself. A USB Type-C port has been placed on the side facing away from the user, and a quick use of the keycap puller shows the use of Gateron Optical Brown switches.
