Polyester 100% serger thread, size 90, 1500m spools. A set of 6 in red and beige tones. Some have been opened, others are still sealed. Even the opened ones were only used for test sewing (or just opened) and have been stored in a cupboard since. I am selling these as I no longer have a use for them. The amount remaining is almost full, but please refer to the images to confirm. For those who understand that these are used items! - Material: 100% polyester - Length: 1500m Brand: Kanagawa Sangyo / Daikoku Shigyō
