This thread is the last of the 4 sets currently for sale. Most are unused or nearly unused. The plastic may have deteriorated, but the contents should be fine. Thank you for your understanding. m(_ _)m 100% Polyester 100 count, 10000m #ミシン糸uniko (Mishin-ito uniko - Sewing thread uniko) I got these cheaply from an acquaintance, and I'm selling the ones I can't use. They were used by someone who made clothes, so I think the fabric is good, but I don't know the material, and I'm not very knowledgeable about fabrics, so I'm selling them at a low price. (Please consider the product images) Perfect for handmade projects! Instant purchase OK. No discounts. #ミシン糸 (Mishin-ito - Sewing thread) #工業用ミシン糸 (Kougyou-you mishin-ito - Industrial sewing thread) #ポリエステル (Posuteru - Polyester) #スパンミシン糸 (Supan mishin-ito - Spun sewing thread)
