Super Strong Magnetic Golf Hat Clip
These hat clips are magnetic and allow you to attach your ball marker to your hat while you're not using it for safe keeping.
These hat clips can also be used to clip to your belt.
Please make sure that your ball marker is made from a suitable metal that will attract to the magnet in these clips.
If your ball marker is already magnetic it may not attract to this hat clip as the polarities may be the wrong way round.
