In addition to the wrist rests, Moon Key sent along four of its keycaps. These shipped in a fancy wooden box—possibly maple. The Moon Key logo is etched into the top, and carvings along the sides add further character to the box itself. Two sets of gold-plated hinges on the back make for a solid-feeling box when opened and closed. On the front is an ornate locking mechanism, opening which reveals the four keycaps snugly packed in individual compartments that have foam all around for protection.
Given their matching theme, I am examining two keycaps on this page. The first adopts the rare dome profile and is the well-named "Eagle Has Landed" keycap. It aims to capture the moment the moon was conquered for humanity, with the US flag planted in the ground by an astronaut, and there's even another lander behind. The dome profile allows for these elements to be added, thus making it a decent practical implementation, too. Should you want it to better match your keycaps, there's an R1 SA profile version too, which is 16 mm tall at the top. The base is the same moon surface texture from before, and the keycap is compatible with Cherry MX-style cross stem switches, making it easy enough to install on the Anne Pro 2. The size and shape of this keycap isn't going to match any other keycap profile, so I placed it on the Esc key as seen above. It ends up being an attention-grabber for sure, and there is enough surface area at the top for the switch to still be pressed when needed.
Speaking of the SA profile, the second keycap uses the very same. It's also a major departure from the inspiring Eagle Has Landed keycap, where one astronaut launched a million dreams for youngsters to go venture beyond mundane life routines. This one, named The Last Astronaut, shows a scary tale of a stranded astronaut drifting through space. It might as well be named The Lost Astronaut too, with no hope left as the last bit of life support in the suit sustains the astronaut with the sheerness of space all around in its beauty and absolute terror. There are two color options for this keycap—blue and black—that have different backgrounds. In fact, this may be the most one-of-a-kind keycap I have seen because even the photos on the product page differ from each other, as does mine from those, with different variations on the space background. It's a good thing then that there's no wrong design here, as they all do a good job depicting the theme. The SA profile is again an R1 unit, so it is also best used for the Esc key, but you can indeed use it alongside other tall SA profile keycaps if that is your jam.
Here are two photos of the astronomy-themed trio together. Moon Key has other wrist rests and keycaps in the theme too, but I do feel these do a good job representing the product family as a whole.
I did take the keycaps to the lab for close-ups under the microscope, which makes for a good example of never getting too close to people or products you admire. The finish on the keycaps isn't as well done as on the Jelly Key keycaps, but admittedly even getting these done with all the challenges COVID-19 has wreaked upon Moon Key is admirable in itself. The figurines lack detail when you get close, and there are multiple regions where the layers bleed over in the bottom. A couple of small air bubbles are seen too, trapped during the resin fill process, and we see that these are both thick keycaps with a wall thickness of ~2 mm.
