JS Ceramic Bobbin

I have not used many other bobbin's besides this one. I go with the ceramic to hopefully avoid grooves that will nicks in the thread. I have 2 of these and so far so good.

Very good bobbin. With the full ceramic tube, you can easily use one of the nylon dental floss threaders. I use a fair amount of GSP thread, and the ceramic holds up as well or much better than anything else. Long lasting and probably a lot stronger than you might be thinking.

With the ceramic tube, no more grooves in the metal tube that causes nicks in the thread. Plus very cost efficient.
