Paper Sided Plastic Core Pre Wound bobbins. Made in USA. ( 58 sec.)
If you are a fan of cardboard side pre-wound bobbins, then this product will certainly charm your operator and increase your production. At 134 yard long, this Style L has a plastic core which eases the thread feed, without any resistance, and also allows the manufacturer in USA, to be constant in the actual winding of the thread. In other normal sided bobbins, the physical presence of cardboard sides makes it a variable when it comes to winding thread at the factory, because it tends to move a bit. However, this plastic core is always the same width, same size, same shape which in the end, makes it a better uniform product. Worth a try!
