This is yarn I purchased online a long time ago. I think it was leftover yarn from a factory. It's part of a large set. Lame yarn I don't know the type. I think it's probably yarn for weaving... The tubes are labeled: kyototex kyowa metallic yarn It's a very fine yarn and can be cut by hand. I don't know the details at all, so I will answer any questions to the best of my ability. I hope someone who can use it will find it useful. It's unused, but I bought it a long time ago, so please purchase only if you understand that. I don't see any discoloration or damage.
