Dear barryb508,
I haven't yet seen a golf ball marker in person, but judging by some photos on websites, you may be well-served by an item like our <Font Color=orange>hat pins</Font Color>. If these are too long, you can clip them to the desired length.
Also guessing, it would seem like <Font Color=blue>scatter pins / tie tacks</Font Color> may not be quite the right item.
Am I on the right track? Or should I get more of a description from you?
