◆ This is Shikibo's 100% polyester button thread. All 36 spools have different colors. The remaining amount is 70-100%. The ones in the bag are unused. Each spool has 330m of thread, making it a much better value compared to button thread on cards. It's also suitable for leathercraft stitching, etc. ◆ Overall, there is some fine dust. Also, there are 5 or 6 spools with slight stains on the top. Please understand the above before purchasing. ◆ Replies to comments will be between 5:00 AM and 9:00 PM. ◆ Instant purchase is OK.
