This is a set of 4 white #90 spun sewing machine threads. These are limited quantity, discounted items, and the color is limited to white. Due to failing inspection, these products cannot be sold through regular channels and are being offered at a bargain price. The reasons for the defects include stains, poor winding, and less than the standard 5,000m of thread. They are still perfectly usable as sewing thread, but please be aware of these issues before purchasing. Made of 100% polyester, the size is approximately 12cm in height and 6cm in diameter, suitable for use with home serger machines. Shipping will be via Yu-Packet Plus.
