Bonjoc is created by Eunice Cho, an accomplished golfer who has competed on the UCLA Women's Golf Team and on the professional tours. After retiring from competitive golf, Eunice became a certified LPGA T&CP Golf Instructor. After starting the Bonjoc company in 2005, Eunice left golf instruction, and devoted her time to growing the line of feminine golf accessories.

The idea of Bonjoc started during a round of golf, when Eunice had difficulty locating her ball marker (a coin) on the putting green. She then thought of creating a ball marker that would "stand out". Bonjoc is still the original creator of the "crystal ball marker".

Since this epiphany, Eunice has come up with over 100 designs using 100% genuine Swarovski crystals to handcraft her ball markers. From cute butterflies to monograms to custom designs, the possibilities for ball markers are endless. Eunice pays close attention to detail with her designs to ensure that Bonjoc represents the finest products available.
