The thread is new and unused. The bag has been opened because a few were used. It will be sealed with tape for shipping. I purchased it online, but I'm selling it because the thread didn't sit well on my home sewing machine, and it was thicker than the #60 thread I usually use, so it wasn't what I expected. The length per spool isn't specified. (Based on how much I used, it seems like there's about 200 meters per spool. Please understand that this is not exact.) - Color: Black - Material: Polyester - Quantity: 6 pieces Thank you for looking.
