The Bernina Overlock Thread Collection by Mettler is a dependable, ready-to-sew set of premium serger threads designed to keep your overlock stitches smooth, strong, and beautifully balanced—and it comes packed in a convenient Bernina storage tin for tidy, easy organization. Featuring Mettler Seracor, this high-quality 100% polyester corespun thread delivers an excellent blend of strength, elasticity, and smooth performance across virtually all fabric types. Seracor is also non-shrinking and easy-care, making it a dependable choice for garments, activewear, and high-wear projects.

Seracor is a 50 wt, 2-ply thread with a matte finish, making it a great choice for everyday seam finishing, construction, and decorative edging. It’s engineered to run cleanly through your serger with dependable tension and strong resistance to breaking, helping you achieve professional results on both lightweight and heavier projects. Inside the tin you’ll find 32 spools, each with 1,094 yards (1000M)—so you’ll have plenty of thread on hand for hemming, seaming, and finishing from start to finish.
