Customer Questions & Answers
-
Question:
What is the PFU Key Top Set PD-KB400KTB Sumi Black?
Answer: The PFU Key Top Set PD-KB400KTB Sumi Black is a premium keycap set designed for the Happy Hacking Keyboard (HHKB) with an English layout. Made from high-quality materials, these keycaps enhance both the aesthetic and tactile experience of your keyboard. Users appreciate the smooth, sophisticated finish that not only looks great but also feels pleasant to type on. This keycap set is especially favored by coding professionals and typists who spend long hours at the keyboard, as it promotes a comfortable and efficient typing experience. -
Question:
Are the keycaps compatible with all HHKB models?
Answer: Yes, the PFU Key Top Set PD-KB400KTB Sumi Black is specifically designed for compatibility with all models of the Happy Hacking Keyboard (HHKB). This includes models like HHKB Professional and Type-S. The design ensures that each keycap fits perfectly onto the keyboard's switches. This compatibility allows users to upgrade their existing HHKB without any issues, ensuring every keystroke feels smooth and responsive while maintaining the keyboard’s iconic layout. -
Question:
What materials are the keycaps made of?
Answer: The keycaps in the PFU Key Top Set PD-KB400KTB Sumi Black are crafted from high-quality PBT plastic. This material is known for its durability and resistance to wear over time, making it a preferred choice for keyboard enthusiasts. PBT keycaps do not shine as quickly with use compared to ABS plastic, thus maintaining their fresh look over longer periods. For those who prioritize longevity in their typing equipment, this set provides an optimal solution. -
Question:
Can the keycaps be customized or replaced easily?
Answer: Yes, the PFU Key Top Set PD-KB400KTB is designed for straightforward installation and removal. Enthusiasts often customize their keycap sets to achieve unique looks or functionalities. These keycaps can be replaced without any specialized tools; simply use a keycap puller for seamless changes. This feature allows users to switch their keycaps for different themes or layouts as needed, making it easy to refresh the look of your HHKB. -
Question:
Do the keycaps offer any unique design features?
Answer: Absolutely! The PFU Key Top Set PD-KB400KTB Sumi Black features a minimalist and elegant design, with legends that are clear and easy to read. The keycap colors provide a sleek contrast that complements a variety of workstation aesthetics. Additionally, the set promotes a deeper level of customization through its unique colorway that many users find appealing. This makes it suitable not only for programmers and typists but also for those who appreciate a stylish workspace. -
Question:
Are these keycaps suitable for gaming?
Answer: While primarily targeted at typists and programming professionals, the PFU Key Top Set PD-KB400KTB Sumi Black can also be used for gaming. The tactile feedback provided by these keycaps allows for precise keystrokes, which is essential for both casual and competitive gaming. Gamers who prefer responsive key actions and a professional aesthetic can find this keycap set enhances their overall experience during gameplay. -
Question:
Can I use these keycaps on a different keyboard brand?
Answer: The PFU Key Top Set PD-KB400KTB Sumi Black is optimized for the Happy Hacking Keyboard (HHKB) and may not fit other keyboard brands due to different switch types and layouts. While some mechanical keyboards use the same Cherry MX style switches, slight variations in keycap sizes and stem fits can lead to compatibility issues. Hence, it's recommended to use this keycap set exclusively with HHKB units to ensure optimal performance and aesthetics. -
Question:
What is the color scheme of the keycaps?
Answer: The PFU Key Top Set PD-KB400KTB Sumi Black features a sleek and modern color scheme primarily in a deep black hue. This minimalist approach not only promotes elegance but also enhances readability and provides a nice contrast against the bright glow of RGB backlighting, should your keyboard have it. The uniform matte surface of the keycaps also gives a premium feel that many users appreciate, especially in professional settings. -
Question:
Will these keycaps change the feel of my HHKB?
Answer: Yes, switching to the PFU Key Top Set PD-KB400KTB Sumi Black will alter the feel of your HHKB slightly due to the different profile and material. Users often report that the PBT material provides a more solid and stable typing experience compared to softer options. This enhances the overall tactile response, which can lead to improved typing speed and accuracy. This keycap set is perfect for users looking for an upgrade to their typing experience. -

HHKB Keyboards PD-KB400KTB Editorial Review
The PFU Key Top Set PD-KB400KTB is a keycap set designed specifically for HHKB English keyboard layouts. The set is not compatible with Cherry switches, as it is specifically made for Topre switches. The keycaps feature a stealthy black print, giving your keyboard a sleek and minimalistic look. However, it is important to note that this set may not work completely with the Realforce R2, as it lacks certain keys including the larger right-shift, arrows, navigation, numpad, alt, and ctrl keys. If you are in need of individual key replacements for Topre switches, we recommend checking out Hot Keys Project and KBDfans. If you have the option, consider purchasing a Realforce Hipro keyboard and harvesting the keycaps for a more complete replacement. Good luck!
