The 100 Pieces Plastic Sewing Bobbins Sewing Machine Bobbins with Case and Sewing Thread for Brother Singer Babylock Janome Kenmore (Transparent) are really nice! They came packaged really well. The cases each hold 25 bobbins. The cases are made well so that each bobbin sits in its own well. So, there aren’t just bobbins floating around inside the case getting tangled. The closure is kind of on the inexpensive side but it works okay. The bobbins fit perfectly with my Kenmore sewing machine and seem to be identical in thickens and have the same hole pattern as the ones my machine came with as far as the indents go. The quality for these bobbins is really nice. I am super happy with how well they function and that there are so many of them. This is a really good value for bobbins.
The bonus thread and soft tape measure are really nice as well. The tape measure Is accurate for the measurement and the thread is great for general sewing.
All in all, this is a really nice set of bobbins. They fit my machine perfectly, they are made really well, and they work great! I would absolutely recommend them!
