The Platinum #3776 Century BTB-10000S is a rare and exquisite ballpoint pen crafted from genuine celluloid — a material celebrated for its vivid, swirling colour patterns and warm, organic depth. Each pen is unique: the natural variation in celluloid means no two pieces are ever exactly alike, making every BTB-10000S a one-of-a-kind writing instrument.

Drawing on the vibrant dyeing qualities and complex colour interplay that only celluloid can achieve, the BTB-10000S is offered in three distinctive pattern colourways inspired by traditional Japanese aesthetics:

Celluloid Pattern Variants

  • Bekko (鼈甲) — A warm tortoiseshell pattern with amber and brown tones, evoking the timeless elegance of traditional Japanese lacquerware
  • Ishigaki (石垣) — A layered stone-wall pattern with cool, structured depth reminiscent of ancient castle masonry
  • Kingyo (金魚) — A vivid, flowing pattern inspired by the shimmering colours of Japanese goldfish
