All of these are DMC embroidery threads. There are 30 threads in total (including 4 bonus threads). 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 noticeable fraying. I don't think there are any duplicate numbers, but please refer to the images. Recommended for those who want to try various colors. The four threads 807, 794, 827, and 807 have color fading and stains. Please see the images for details. These four threads are bonus items. Please understand that these have been stored at home for a long time, so please check carefully before purchasing. ⭐️ I plan to list other colors as well.
