This article covers Ducky KeyCaps 31セット ゴム製ダブルショットバックライト Ducky KeyboardまたはMX対応 31キーキャップセット ネイビーブルー.

Overview

The Ducky KeyCaps 31-Set Rubber Double-Shot Backlit Keycaps in Navy Blue is a specialized keycap set designed for mechanical keyboards. Produced by the well-known Taiwanese brand Ducky, this set includes 31 keycaps made from rubber and transparent ABS material, featuring a diamond-textured rubber top for enhanced grip. This product targets gamers and typists who want improved tactile feedback and control on frequently used keys. The rubber coating provides a non-slip surface that helps maintain accuracy during intense gaming sessions, while the double-shot molding ensures the legends won't wear off over time. It's a practical upgrade for anyone looking to enhance their keyboard's feel without replacing the entire set.

Connectivity & Compatibility

The keycaps are compatible with all Ducky keyboards and any mechanical keyboard that uses Cherry MX-style switches. This includes popular switch brands such as Cherry MX, Gateron, Kailh, and Outemu, as long as they have the standard cross-shaped stem. The set includes keycaps in multiple rows: R4 (Esc, 1-6), R3 (Q, W, E, R), R2 (A, S, D, F), R1 (2.25u left Shift, Z, X, C, V), and R0 (Ctrl, Win, Alt, Spacebar, 4 arrow keys). It also includes an ISO 1.25u left Shift and a 1u backslash, making it suitable for both ANSI and ISO layouts.

Product Info

Released around 2021, the Ducky KeyCaps 31-set is available on Japan for approximately ¥17,894 (tax included). Warranty follows Ducky's standard policy, typically covering initial defects but not normal wear and tear on consumable items like keycaps. In terms of market positioning, this set sits at the entry-to-mid level. It's not a full keyboard replacement but a targeted upgrade for the most-used keys. The price reflects the specialized rubber coating and double-shot construction, which offer better durability and grip than standard ABS keycaps.

Best Use Cases

First, competitive gamers who play FPS or battle royale titles will benefit most. The rubberized surface on WASD, Shift, Ctrl, and Spacebar provides a secure grip even during sweaty sessions, reducing the chance of slipping and improving reaction times. Second, mechanical keyboard newcomers looking to dip their toes into customization will find this set approachable. With only 31 keys to swap, it's less intimidating than a full set and lets users experience the difference in feel without a large investment. However, users who want a uniform look across the entire keyboard—including the number pad, function row, and navigation cluster—should look for a full 104/108-key set instead. This set is strictly for partial replacement. ## Alternatives
In the same price bracket, the HyperX Pudding Keycaps (around ¥2,000-3,000) offer a translucent design that lets RGB lighting shine through, but they lack the rubber grip. The YMDK Double-Shot PBT Keycaps (around ¥3,000-5,000) provide excellent durability with a smooth finish, but they can feel slippery during fast gameplay. The Ducky set stands out for its superior grip and targeted key selection, making it the best choice for gamers who prioritize control over full coverage.

Things to Consider

This is a 31-key set, so it won't cover your entire keyboard. Missing keys include the number pad, function row, and navigation cluster. The rubber coating may degrade over time, becoming sticky or worn, though the double-shot legends will remain legible. Also, the keycap profile differs from stock keycaps, which can alter the typing feel. Before purchasing, verify that your keyboard's key sizes match the included caps, especially the spacebar and left Shift.
