All numbers (10, 30, 50, and 80) are available at a flat rate, so please comment if you need them. The length is +150 yen for every 10 meters. This is an ultra-strong thread perfect for restringing Akoya pearls. It is used by professional pearl stringers and is so durable that it's difficult to cut even with scissors. Buying a whole roll is too expensive and too much... How about a 20m pre-cut length? We will prepare the thread after you order, wound on a card, with a length longer than 20m (approximately 22 meters). I used it to restring a pearl necklace, and it was smooth and easy to use. Various restringing methods are uploaded on YouTube, and even beginners can finish it in about 40 minutes. The image is for reference only; this listing is for the pre-cut thread itself. It seems to be good and sturdy as a sewing thread for handmade items. It may be difficult to cut unless you have sharp scissors. Please understand the nature of flea markets. We will ship via Yu-Packet Post Mini with simple packaging. Returns and exchanges are not possible to prevent trouble. Please understand. #GPT thread #Gunze #Pearl necklace #Restringing #Pre-cut
