Nexbelt Ball Marker

I just American Flag buckle. What is purpose of it flipping open?

Hi Mike - we have a couple version of the American flag buckle. One is the normal buckle and the other is a Go-In - it is a golf buckle. The face flips open and has a hidden ball marker to mark your ball in golfing.
Hope that answers your question.

What size strap fits this buckle

Hi Lynda - any straps that is 1 7/16. Which is about 90% of our straps.

I just bought 2 new belt ball markers. I thought one side had an N and the other side had an arrow and words, move back. Both mine only have an N on one side. Was I incorrect?

Hi Tom - Sorry about that. We will send the correct ones immediately.
