To make it more affordable, I've created a set that includes shipping and fits in an 80-size cardboard box. The materials are varied. The purchase dates back over 20 years. I haven't used them in 10 years, and they've been stored in a case. However, I'm selling them at a reduced price because I've gathered only the threads with noticeable stains. The condition varies, including items with overall noticeable stains, items with small spots, and items that I thought were dirty but don't seem to be so noticeable upon closer inspection.
