The new innovative plastic Dreamlit Shuttle from Handy Hands is, posted with a bobbin, and a steel hook. ,The shuttle is held together with very strong magnets.
It has 2 bobbins and a winder but can easily be used as a post shuttle by simply removing the bobbin. Because the shuttle pulls apart it is so easy to load and unload the bobbin for a quick change of thread, the shuttle 'snaps back together holding the bobbin tightly but still allowing ease of use without the bobbin becoming too loose.
It is 2.75" excluding hook x .75 wide. The pack includes shuttle, 2 bobbins, a winder and is available in 5 different colour ways.
