This one's fore the ladies! (Or maybe guys...to each their own)

These markers are as durable as the iconic mugs they are designed after.

Standing at 1.5" tall and about 11/16" wide (at the handle) and 2MM thick, the Magnolia Golf Birdie markers are the perfect size to mark your Birdie putt.  

Buy one for yourself or the whole collection for your four-some.
