Description
The Apollo hook is a system from the horizontal hook group and does not require a bobbin case and has low thread tension. For machines with the special Apollo hook from SINGER, the Prym range includes a pack of four matching sewing machine bobbins made of transparent plastic.The big advantage of plastic bobbins is that you can always see the color of the thread and how much thread is left on the bobbin, thus avoiding sudden running out of the lower thread. However, when choosing a bobbin, you should always consider the material of the hook, as otherwise either the bobbin or the hook may wear out prematurely.
