Leifide 4 Pieces Stainless Steel Bobbin Case Compatible with Juki Ddl-5550 Ddl-8100 Ddl-8300 Ddl-8500 Ddl-8700 Single Needle Sewing Machine for Front Loading

This is a part that will last forever if you don't drop it and have it hit the floor and bend, but I'm human.

This bobbin replaced the original factory bobbin &wotks perfectly!!!

I like the price, I took a chance on this one, just carefully examined the bobbin case that I had inside and out. The inside has a thin, blue metallic "springy thing" that my old bobbin case had. For those with bobbin case problems, sometimes it's old thread wound around the inside of the sewing machine. Just unscrew the plate and pull and cut the thread.

Fits elna elnita ef1. A little oily out of the bag but can easily be wiped down a little. It's good that it comes a little oily so that the metal doesn't rust over time while sitting in the bag. Inside blue part tends to be flattened out but can be easily fixed with a small tool to help bend the blue metal up a little bit. Test one of them out on my elna elnita ef1 and works perfectly. Price is good too.

The media could not be loaded. I have a Brother PQ1500sl, and these are exactly like the bobbin case that was included with my machine. Four bobbin cases were included in the box. You will have to make the tension adjustment. After I made the adjustment, my machine hummed along like it did with the original bobbin case, and the stitches were perfect.

Trabaja muy bien

Works fine on my Vevor Machine.

Just what I ordered it fits both my industrial machines received it earlier than expected
