Yellow dot bobbin case for Janome emroidery machines #846652700 | Bobbin cases

The yellow dot bobbin case has twice the amount of tension as the standard bobbin case (red mark). You can use this bobbin case whenever the bobbin thread is finer than the needle thread, to prevent the bobbin thread from slipping to the top of the work. During normal embroidery it is recommended that you use the high tension bobbin case (yellow dot).

For use with: Janome MC15000, MC12000, MC9900 Horizon, MC350E, MC500E; Elna EL900 eXpressive, EL860 eXpressive.
