Coral Sea Keycap Five-Sided Keyboard Custom PBT Keycaps OEM Height 110 Keys 6.25U Space Style Options A B C D Mechanical Keyboard Accessories
Coral Sea Keycap Five-Sided Keyboard – Custom PBT Keycaps in OEM Height

Upgrade your mechanical keyboard with the Coral Sea keycap set, offering a full complement of 110 keys including a 6.25U space bar. Made from PBT material with a five-sided sublimation process, these keycaps deliver clear legends that resist fading from extended typing sessions. The OEM profile height matches the familiar stepped rows found on most factory mechanical keyboards, so the transition feels natural. Four colour styles (A, B, C, D) provide options for both subtle and bold setups. This set covers full-size layouts and most tenkeyless (TKL) boards, giving you a cohesive visual upgrade without compatibility guesswork.
Features and Construction

Built around practical materials and consistent manufacturing, this keycap set prioritises longevity and typing consistency. The five-sided sublimation process inks legends across the top and all four sides of each cap, ensuring the lettering stays sharp under daily use. PBT plastic is chosen for its resistance to the shiny polish that develops on softer ABS caps over time. OEM profile means each row has a specific height and angle, matching the contoured shape of standard mechanical keystrokes.
Material and Build
Each keycap is injection-moulded from PBT, a harder plastic that retains its texture and resists wear. The five-sided sublimation process applies dye that bonds with the plastic, creating legends that do not chip or rub off with normal typing. This method also allows for complex multicolour patterns across the keycap surface. The result is a set that stays looking new longer than painted or pad-printed alternatives.
Size and Practical Fit
The set includes 110 keys, with a 6.25U space bar that fits standard Cherry MX and compatible switch stems. OEM profile heights are consistent: row heights start lower at the top of the keyboard and rise towards the middle before dropping back down, matching most mechanical keyboard layouts. Before installing, check that your keyboard uses a standard bottom row spacing for the 6.25U space bar and that stabilisers are compatible.
Uses and Placement

These keycaps suit a range of mechanical keyboards, from gaming rigs to daily typing stations. The four style options let you personalise your board without committing to a single colour theme. The PBT material and OEM profile make them a drop-in replacement for many stock keyboard sets, requiring no special tools beyond a standard keycap puller.
Event or Professional Use
For shared office environments or LAN events, the subdued style options blend in while the PBT surface resists wear from multiple users. The five-sided legends remain legible under direct lighting, reducing glare and making key identification easier in bright conditions. The set’s full-size coverage suits full keyboards with number pads commonly found in professional settings.
Everyday Home Use
At home, the textured PBT grip helps maintain finger placement during long typing or gaming sessions. The OEM height provides familiar key travel without forcing an ergonomic adjustment. The four style choices allow you to co‑ordinate with your desk aesthetic, from minimalist to colourful, depending on your selection.
Benefits and Buying Value

Replacing factory keycaps with this Coral Sea set extends the visual life of your keyboard without replacing the entire board. The five-sided sublimation process and PBT construction reduce the need for future replacement due to faded or shiny caps. The included 110 keys and 6.25U space bar cover a wide range of mechanical keyboards, making this a versatile single purchase.
Reuse and Low Maintenance
PBT keycaps resist the oily gloss that develops on ABS sets, so the surface texture stays consistent for longer. Cleaning requires only a wipe with a damp cloth—no special solvents or polishes. The sublimated legends do not peel or crack, so the set can be transferred to a new keyboard if you upgrade your board later.
Why Choose This Product
With a choice of four colour styles, PBT material, and five-sided sublimation, this set delivers a custom look backed by proven manufacturing methods. The OEM profile ensures immediate compatibility with most mechanical keyboards, and the 110‑key count covers both full-size and tenkeyless layouts. If you want a durable, fade-resistant keycap set that matches factory key travel, the Coral Sea line offers a grounded upgrade path.
