100 % cashmere yarn set. Perfect for weaving and knitting/crochet. Colourmart yarns are end of line from high end manufacturers but often have knitting machine oil in the fibre. This washes out. I can't detect any smell on mine so they may not have it. Please adjust if using in a knitting machine. I was going to knit with them but my hands are too shakey to deal with laceweight yarn and needles.
