■ Woolly Lock Serger Thread (Set of 4) Red and Bordeaux were used once and then stored. Black and natural were used quite a bit, so there is not much left, but I am selling them as I no longer have the opportunity to use them. I would appreciate it if you could judge from the images. For those who understand that these are used items! - Color: Red (13) - Color: Bordeaux (18) - Color: Natural (403) - Color: Black (402) - Material: 100% Nylon - Weight: 25g - Thickness: 122 denier
