Prewound Bobbins with Polyester Thread, Suitable for Class 15 Sewing Machines

DOUBLELIN has been a professional manufacturer of embroidery machines, DTG printers, and machine parts since 1989. As experts in threads and bobbins, we understand the intricacies of the machines that utilize these components, which has helped us better comprehend the needs and preferences of our customers.

Quality is our top priority. We source materials only from large, qualified suppliers, and each batch undergoes rigorous testing to ensure strength, fineness, and evenness. Despite the high cost of materials, we manufacture our products in-house and sell them directly to customers, allowing us to offer affordable prices.

Our professional expertise extends to the bobbins themselves – we know how to ensure they function optimally and understand the key points related to their integration with various machine models. Before launching a product, we thoroughly test it on machines and collect feedback from end-users.
