I never saw a bobbin case with a wick! Must be on the newer machines. The youngest I have is 26yrs old! One I'm teaching granddaughter to sew on is 72+. And all are working great! LOL I am proud to be teaching her on the machine that I tought myself on in the 50s. She is 10 yrs old and visiting us from Florida. Have her making a small Sudoku quilt. Hope to have it finished when she goes back to Mom and Dad on Sat. Going to miss her terribly.
