That's because pre wounds in large quantities were originally for commercial machines. Domestic use machines didn't have pre wounds at all until several years ago, and even then, they were made for embroidery machines. You'll find that the pre wounds are a much thinner thread, 60wt or 90wt thread. Janome pre wounds also come in a 12 pack but you can get white, black, or a combo pack.
