They are consumables, and early replacement is recommended as they are less likely to have scratches or distortions that affect thread tension. Made of aluminum, they are lightweight and rust-resistant, making them easy to care for and helping to stabilize thread tension. The grooved design also allows for smooth setting on the bobbin winder. We will deliver new, inspected products. ★ About Shipping ・ We ship three times a week: Mondays, Wednesdays, and Fridays. ・ On holidays, we will ship on the next day or the day before. ・ We ship as early as the next day after purchase. ・ It takes about 4-7 days via regular mail. ・ The shipping schedule for long holidays is listed in my profile. ★ About the Product ・ New and unused.
