P610363 - Bobbins horizontal shuttle plastic 21.2mm x 4pc

P610363 Prym Horizontal bobbin hook. This is a system which works without a bobbin case and with a low thread tension. For machines with this bobbin type the range offers packs with four of the same bobbins made of transparent plastic in three different sizes. A major advantage of a plastic bobbin is that you always see the colour and quantity of thread remaining on the bobbin and in this way can prevent the sudden failure of the lower thread. Available for the brands JANOME, BROTHER, SINGER, BERNINA, HUSQVARNA and PFAFF in each corresponding version. 610363 21.2mm 4pc
