The Apollo bobbin hook system is part of the horizontal bobbin hook category, eliminating the need for a bobbin case and functioning efficiently with minimal thread tension. For SINGER brand sewing machines equipped with the special Apollo bobbin hook, Prym offers this convenient assortment of four corresponding bobbins made from transparent plastic.

Plastic bobbins offer a significant advantage, as they allow you to continuously monitor the thread's color and remaining quantity, thereby helping to prevent abrupt depletion of the lower thread. However, when selecting a bobbin hook, it's essential to consider the material, as neglecting this aspect may lead to rapid wear and tear in either the bobbin or the hook.
