Just when you thought it was safe to play the green with a standard golf ball marker, artist Nikki Heikkinen surfaces with this wildly cool alternative. A ferocious choice for any golfer who strives to make a strong impression, each one is handcrafted of thick stainless steel, so its unmistakable shark-fin shape clearly marks the position of your ball for all to see. The thought of a monstrous, toothy shark floating below that fin may just shake up the competition and cause a frenzy on the course. Made in Wisconsin.
