Best Custom Keycap Materials Guide

The material of a keycap influences:

• Typing Feel – PBT offers a matte, slightly textured surface that resists shine, while ABS feels smoother but can become glossy over time.
• Sound Profile – Thicker PBT or resin caps produce a deeper "thock," whereas thin ABS caps can sound sharper.
• Durability – PBT and metal caps are highly resistant to wear and shine, whereas ABS can develop a lacquered shine after months of use.
• Aesthetics – Resin and dye‑sublimated PBT allow vibrant, detailed designs that won’t fade, while double‑shot ABS gives bright, uniform colors.
• Compatibility – Certain materials (e.g., resin, metal) may be taller or heavier, affecting key travel and stabilizer performance on compact layouts.

1. Identify your priority – If you want a long‑lasting matte feel, go for PBT. If you crave unique artwork, consider resin or dye‑sublimated PBT.
2. Check profile & size – Most custom sets use Cherry, OEM, or SA profiles. Ensure the set matches your keyboard layout (60%, 65%, 75%, TKL, full‑size). The Womier Pink Shine Through set, for example, is Cherry profile and fits 60%‑100% boards.
3. Consider thickness – Thicker caps (>1.5 mm) feel more solid and reduce flex but may require stronger stabilizers. Thin caps are lighter and good for fast typing.
4. Look at manufacturing method – Double‑shot molding guarantees color integrity, while dye‑sublimation offers intricate patterns without layering.
5. Read reviews & ratings – High ratings (>4.0) and substantial review counts (e.g., 429 reviews for the Womier set) indicate reliable quality.
6. Budget vs. rarity – Standard PBT sets are affordable (≈$13–$30). Artisan resin caps are pricier per piece but add distinctive flair.
7. Compatibility with keycaps accessories – If you plan to mix artisan caps (like the Yellow KOI resin cap) with a full set, ensure the base set uses a compatible stem (Cherry MX).

1. Regular cleaning – Remove caps and soak in warm soapy water (avoid harsh chemicals). For resin caps, use a soft brush to prevent scratches.
2. Avoid exposure to UV light – Prolonged sunlight can fade dye‑sublimated colors on PBT.
3. Lubricate stabilizers – Thicker caps can strain stabilizers; apply appropriate grease to keep keys quiet.
4. Keycap puller – Use a proper puller to avoid stem damage, especially with delicate resin or metal caps.
5. Storage – Keep spare artisan caps in a soft pouch to prevent chipping.
