Bundle of 3 Large 1422 Yard Spools of Aurifil 50wt Egyptian Cotton Thread, Color: Natural White, No. A1050-2021

Q: Are these spools that will fit on a regular sewing machine or are these cones?

they will fit a regular sewing machine. However, one of the spools had the thread coming out of two places in the middle of the top - no way to start using it.
