These are brand new in the package racks that are made by Bernina that I am now stocking.
They can be used as replacements or additional racks to your Barbie acessories case.
They also can be used in the custom 4 sided rotating cases I have been making and listing for sale.
 These racks hold the larger bobbin that is very close to the diameter of a quarter, or 1 inch-diameter.
