GOLFINK Marker Pen

Definitely stays put. It’s a little difficult to control the ink but once it dries it looks like it’s going to stay.

first pen very faint. had to shake it a lot to get any solid colour out. rather surprised. felt like it was old and had dried out. can't comment on longevity yet was supposed to play today but it's raining hard. Rick Shields recommended them so my one must be a dodgy pen.

This product works as advertised! I am extremely happy with the purchase and recommend it to all golfers.
