3% キュプラ (cuprammonium rayon)

From official page:

Estrela, meaning “star”, compares the luster of lamé to a star twinkling in the night. A 3 color star print is dyed on mixed spun thin cotton slub for a fun yarn that weaves using many colors combined with fine gradient dye and lamé threads. This is an ideal very fine thread for knitting delicate crochet hook patterns.
