This is a set of 20 hand-sewing threads, 100% silk, size 9. * Kin-hidori (80m) x 15 * Miyakodori Hane (40m) x 5 Please refer to the comparison photo on the second image. The thickness is about the same as between machine thread and buttonhole thread. All are unused silk threads, still wrapped in cellophane, but they are pre-owned items stored at home, so some of the cards may be discolored or dusty, and the thread strength is unknown. I have selected threads that do not appear to be discolored, but I cannot see inside, so I do not know for sure. The colors on the screen may appear different from the actual colors. Please take a close look at the photos and only purchase if you understand. I am also selling other silk threads. If you purchase multiple items, I can offer a discount on shipping, so please contact me before purchasing. ↓ #pinkiipinkSilkThread #pinkiipinkCraftSupplies
