Bonjoc is created by Eunice Cho, an accomplished golfer who has competed on the UCLA Womens Golf Team, and on the professional circuit for five years. She is now a certified LPGA T&CP Golf Instructor. She separates her time giving golf lessons and devoting her time to Bonjoc.

Bonjoc started during a round of golf, when Eunice had difficulty replacing her ball on the putting green. Worried that she would hold up her group, she thought of creating a ball marker that would "stand-out".

Since this epiphany, Eunice has come up with over 50 designs using 100% genuine Swarovski crystals to handcraft her ball markers. In addition to the sought-after Four-Leaf Clover, Heart, Flower, and Cherry design, Eunice also creates Monogram ball markers for those that like to personalize their game. Eunice pays close attention to detail with her designs to ensure that Bonjoc represents the finest products available.
