Made for the BIRDIE79 Golf Ball Marker. I usually throw a sharpie in the bag and recently got this ball marker. I was worried about it breaking if it got squeezed or hit in the wrong way when moving the bag around. Was going to just keep a ball in it, but then noticed that sharpies seemed to nestle right in to the curves in the design.
Printed with PET-G since I plan on leaving it in my bag which is subject to some heat from time to time in the trunk of the car.
