All of these are DMC embroidery threads. There are 30 skeins in total. I received these after they were stored at home for many years. They are supposedly new and unused, but some may have fraying or fading. Please check the images for any fraying or other issues that I noticed. I don't think there are any duplicate numbers, but please refer to the images. *The last image shows 6 skeins with noticeable fading or fraying. *Please be aware that some of the blue threads have noticeable fading, which is shown in the images. Recommended for those who want to try various colors. These have been stored at home for a long time, so please check carefully before purchasing. ⭐️I plan to list other colors as well.
