You have pre-wound bobbins style L and style M, what is the difference?
There are 2 sizes of pre-wound bobbins and most machines will use style L, which is commonly known as the small ones, about the size of a nickel. The style M (used on many Brother machines and early 90's Tajima machines) is commonly known as the bigger bobbins, about the size of a loonie. At Superpunch, we offer this style L bobbin in 2 ways: the classic finish with cardboard sides at $19.99 per gross and the original Magnu Glide Magnetic bobbins. The style M comes with cardboard sides at $29.99 per box of 144.
