CannonKeys unveils PFF low-profile PBS keycaps with two colorways

CannonKeys introduced PFF, short for Penguin Flat Foot, as a new low‑profile uniform keycap profile designed by Matt3o and manufactured by Keyreative, and announced two initial colorways tied to the Bullet Train group buy. Prototypist lists "PFF Verdant Retro by Orin" with the product blurb "Classic beige with some dark green flare! High quality PBT dyesub keycaps for low profile keyboards," and shows the group buy closing Mar 8, 2026, 11:30 pm with an expected shipping time of Q3 2026.

The company copy describes PFF as uniform in height: "PFF, short for 'Penguin Flat Foot', is a uniform keycap profile- every row has the same height." CannonKeys lays out the geometry in exact terms: "PFF uses a combination of a cylindrical front and back with a spherical top scoop. The result is a wide scooped contact area at the top, which enables a comfy and ergonomic typing experience while maintaining the a lower profile compared to its PBS counterpart." The profile design is explicitly pitched as a low‑profile spin on the long‑running PBS family and was tailored by Matt3o to fit the space constraints of low‑profile switches.

Material and build details are consistent across listings and coverage. TechPowerUp reports "Both keycap sets have 1.5 mm wall thicknesses and dye-sublimated printing," while CannonKeys lists "Keycap Material - Dye‑sublimated and/or Reverse dye‑sublimated PBT." TechPowerUp also notes stem style in the product excerpts: "The stems on the available kits are MX-style, meaning they will be compatible with [...]" which appears truncated in the source text. The combined sourcing indicates PFF kits use PBT with dye‑sublimation legend work and a relatively robust 1.5 mm wall.

Kit availability and variations are narrow at launch. TechPowerUp notes the only PFF sets currently available on CannonKeys are WoB and Verdant Retro. The Verdant Retro listing on Prototypist credits Orin as the designer for that colorway and reiterates the group buy status: "This is a Group Buy - that means this product has not yet been manufactured. This product will ship at a later date, as detailed in the product description below."

CannonKeys places standard group buy terms front and center: "This is a group buy, which means our group buy terms and conditions apply. The estimated date of delivery is just that - an estimate. Delays and setbacks may occur. Upon purchase, you will be charged immediately. And by purchasing this item, you acknowledge everything stated above. For cancellation and refund policies on this order, please refer to our policies and FAQ." The vendor also warns that renders may differ from production: "Colors in the final product may vary since renders are done under idealistic artificial lighting."

What remains unstated in the listings is a retail price and detailed kit contents such as full key counts or compatibility kits. Prototypist and CannonKeys give the explicit deadline of Mar 8, 2026 for the group buy and an expected Q3 2026 ship window, leaving pricing and final samples to be confirmed as the Bullet Train group buy progresses.
