Tray for Style-L Bobbins (Consew 199R, 230, Juki DDL 5550 etc)
Each tray will hold 14 Style-L bobbins (on average they are 21.2mm in diameter and 9.2mm 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). See list of sewing machines that use this style of bobbin below.
A dust cover lid is available as an option (it just sits on top and is not connected to the tray - see picture).
Here's a partial list of machines using the L-Style bobbins:
