PBTfans Sputnik-1

Drawing its core inspiration from the cool tones of Sputnik-1, this keycap set is elegantly highlighted by iconic Soviet-era retro red and bright yellow accents. The novelty keycaps are rich with historical references: the era-defining hammer and sickle emblem; the orbital path tracing the satellite's 21-day celestial journey; the 'OKB-1' manufacturer's mark; and its Harvard designation, 'Alpha 2.' The set stands as a tribute to this satellite's short but glorious venture into space.

The main material of the keycaps is PBT, but we have incorporated "glass microspheres" into the design. Unlike conventional PBT, this unique blend produces a clearer, crisper sound, giving it a Hi-Fi quality. The keycap thickness is approximately 1.3mm, and the surface texture offers a skin-like feel, distinctly different from our dual-color surface.
