The German brand Gunold has released a new generation of disposable embroidery machine bobbins – Signature Magnetic. The bobbins consist of a 100% polyester continuous filament with a magnetic core inside.
This allows you to create a consistent feed and the required thread tension during embroidery. The bobbins save a lot of time since there is no need to wind the thread yourself.
Bring you to mind that disposable Style L bobbins from the cardboard are also popular. You can find them in the catalogs of Madeira, Gunold, and other manufacturers. They are easy to dispose of and completely environmentally friendly.
