The Qualities Behind Every Thread

Designed in Kyoto and crafted with care in Japan. Three qualities define COSMO® No. 25—how it feels in the hand, catches the light, and brings embroidery to life.

Close-up of extra-long staple cotton fibers

Premium Cotton

Carefully selected extra-long staple cotton—valued for strength, softness, and a naturally smooth surface.

COSMO embroidery floss with a silky sheen

Silk-like Luster

A refined sheen adds depth and dimension without an overly glossy look—so the embroidery stays the focus.

Lasting Color

Advanced dyeing and quality control keep colors vibrant over time—and consistent from skein to skein.
