Learn how to pick shine-through keycaps for your RGB keyboard setup. Compare PBT vs PC materials, dual-shot vs prism designs, and find the right fit for your build.
Quick answer
Choose PBT double-shot keycaps for durable, wear-resistant legends and consistent shine, or PC prism keycaps for a more dramatic light-diffusing effect. The Attack Shark SK06 and SK07 are two strong options depending on your priority.
Material and construction matter for longevity and light diffusion
Shine-through keycaps rely on translucent materials to transmit RGB light from your keyboard's switches. The two most common materials are PBT (polybutylene terephthalate) and polycarbonate (PC). PBT is known for its durability and resistance to wear, while PC offers a clearer, more glass-like appearance that can diffuse light more evenly.
The construction method also affects how legends (the printed letters or symbols) hold up over time. Double-shot injection moulding embeds the legend into the keycap material, so it won't rub off. In contrast, pad-printed legends are cheaper but can wear away with heavy use.
Design determines how RGB light appears on your keyboard
Not all shine-through keycaps are created equal when it comes to the visual effect. Some designs use side-positioned legends and topographic line patterns to channel light in specific ways, creating a more uniform glow across the keycap surface. Others use a prism-like structure with transparent edges that make each key appear as a separate light island.
Your choice depends on whether you prefer a consistent, evenly lit look or a more dramatic, segmented light effect. The former works well for a clean, professional RGB setup, while the latter can make your keyboard stand out with more visual depth.
Decision rules for choosing shine-through keycaps
- If you prioritize durability and consistent RGB glow: Choose PBT double-shot keycaps like the Attack Shark SK06. The legends are embedded and won't wear off, and the dual shine-through design provides even backlighting across the entire keycap.
- If you want a dramatic, segmented lighting effect: Choose PC prism keycaps like the Attack Shark SK07. The L-shaped transparent structure and suspended design make each key appear as a separate light island, creating a more visually striking RGB effect.
- If you need compatibility with non-standard layouts: Check the keycap set size and layout support. The SK07 includes 131 keys (100 custom prism keycaps plus 31 fully transparent PC keycaps) and supports wide layouts, while the SK06 offers 135 keys with ANSI/ISO compatibility. Verify your keyboard's layout before purchasing to ensure full coverage.
Product facts

Dual shine-through design with side-positioned legends and topographic line patterns both transmit RGB light. This means the legends won't fade or rub off, and the RGB backlighting will be evenly distributed across the keycap surface for a consistent glow.
