Nautilus Has a New Dark Side

Zambumon’s Twenty Thousand Leagues Under the Sea–themed keycap set, GMK Nautilus, captured the spirit of the open sea. His latest keycap set takes place in the same universe—but it brings the colorway to a darker, more sinister place. Introducing Nautilus Nightmares: a deep green spinoff evoking the frightful Cthulhu sea monster. A monstrous array of greens, dark greens, and darker greens, Nautilus Nightmares is made of durable ABS plastic and sculpted in GMK’s popular Cherry profile.

Note: To avoid confusion with the current checkout system, we will be changing the price points manually. We are paying attention to the number of child kits being bought as well. If they reach certain quantities, we will adjust their prices accordingly. You may notice fluctuations in your checkout price as we make these adjustments on the back end, but you will not be charged more for anything.

If you have an active order that hasn't completed yet and you want to make any adjustments to it, please cancel the order on your transaction page and re-order with your desired kits. This will ensure there are no payment errors when the run ends.

MOQ Policy: If we decide to cancel any kit(s) after a run concludes, we will reach out to everyone whose order contains said kit(s) and give the options to either keep the remainder of your order or to cancel your order entirely. Sometimes kits are made even if they don’t meet MOQ, so it's best for everyone to order everything that is desired. Canceling before the run ends reduces the total number of kit orders, thus reducing the odds that every kit will be made.

About Zambumon

In the words of keyboard enthusiast Zambumon: “Keyboards are the interface between a person and a computer. They’re an indispensable tool for most people's jobs, so they better be good.” The Spanish designer has been involved with mechanical keyboards since 2015—and his work has made a notable impression on the growing community. Some of his most well-known projects include Amazing Chocolatier, a brown and gold set inspired by Roald Dahl’s classic Charlie and the Chocolate Factory; Nautilus, a deep-sea tribute to Jules Verne’s Twenty Thousand Leagues Under the Sea; and Jamón, a red set that honors Zambumon’s native Spain’s delicious cured ham.

Core Kit

The Core Kit is the starting point for everyone. Comprising 136 keys, it provides basic layout coverage for boards ranging from 60%, 65%, 75%, TKL, 96-key, 1800, CP and Fullsize layouts in both standard and winkeyless variants. Some notable inclusions are the accent enter and escape, split backspace, and stepped caps lock keys.

Forties Kit

The Forties kit provides extra layout coverage for many small-form-factor and ortholinear keyboards, including Planck, Minorca, Sebright, or Percebe. The kit includes small space keys, and enter and escape accent keycaps.

Extension Kit

This add-on kit extends the Core Kit’s layout support by providing multiple shift keys in 2.25, 2.00, and 1.00 units sizes. This is ideal for FC660-like and 60% keyboards with arrows, small space keys, and a second B for split and ergonomic keyboards such as the EM7, Alice or Lubrigante. It also provides extra layout coverage for 60%, 65% and 75% keyboards.


The ISO kit adds layout support for German and UK ISO keyboards.

Novelties Kit

Featuring the Nautilus submarine, Kraken, and Giant Waves, the novelties kit will give you the extra touch to take your keyboard even deeper under the stormy ocean.

Space Keys

The Space Keys Kit includes accent space keys from 1.00C to 7.00C for both standard, split, and 40% keyboards. On top of that, this kit will extend your layout coverage by including two 6.00C space bars, so you can cover an HHKB or Cherry G80-1800 keyboards.
