Superior Beka Needles
I found these cleaning out cabinet. I probably picked them up at a yard sale with other things. Can anyone tell me what these are used for? I tried to google them but got nothing for the size I have. I think they may be for a serger but not sure. They are 18/110 in size with some other numbers I don't know what they mean. 62x43, 149x3, DVx43. They are a box of 100.
