Set of 8 wool yarns in various colors, perfect for knitting. - Colors: Pink, gray, green, brown, white - Material: Possibly wool or acrylic - Quantity: 8 yarn balls - Weight: Approximately 500g (estimated) Thank you for looking. The weight including the box is 2.5 kg. These yarns were used with a knitting machine. They have been stored at home. I used to knit with a Brother knitting machine, the "Paris," so I have a lot of industrial yarn. How about using them for practice? For reference, I have wound them onto yarn bobbins. I have a long-haired cat, so please refrain from purchasing if you are concerned. Thank you.
