Callaway utility club head number chips. For those who have lost them. Available numbers: 13.5, 15, 18, 16.5, 20. I had these as spares in case I lost one, but I'm selling them because I'm selling my clubs. They are new and unused, but I've listed them as "near new." Please check the condition in the images. Please refrain from purchasing if you are sensitive to minor imperfections or are looking for a perfect, pristine item. Thank you. Type: Cover
