Tray for Style-A (Class 15) Bobbins
Each tray will hold 12 Style-A bobbins, also called Class 15 (on average they are 20.5mm in diameter and 11.7mm in height, although the height can vary slightly from manufacturer to manufacturer). The bobbins in the picture are only for display purposes - no bobbins are included with your purchase.
The unique feature is the v-slot which secures the thread and keeps the partially or fully wound bobbins from unraveling (insert bobbin with the thread coming up from the bottom and pull thread down into the slot).
A dust cover lid is available as an option (it just sits on top and is not connected to the tray - see picture).
The Style-A or Class 15 bobbins are used in many non-industrial sewing machines. please check to make sure your machine uses these before ordering. Or message us with the make and model of your machine and we'll confirm whether you bobbins will fit in the tray.
