Sewing Machine Bobbin Holder - Drawer Tray (Class 15)

A clean, low-profile tray that keeps your sewing machine bobbins upright, separated and easy to grab. Each bobbin sits in its own curved pocket, so it won't roll around, unwind or tangle, and you can see every colour at a glance.

BOBBIN COMPATIBILITY

The pockets (26 mm trough, 12 mm slot) are made for Class 15 bobbins (about 20.5 mm diameter x 11.7 mm tall), used by many Singer, Janome, Brother and Juki home machines. They also fit Class 15J, Class 66 and L-style bobbins.

Please measure your bobbins before printing: some brands use their own bobbin sizes.

- No supports needed. Every overhang is a gentle curve that faces upward.

- Finger notches in the dividers to lift bobbins out easily.
