Nothing says I love you quite like testicle-shaped jewelry.

SAXX Underwear is out with a fancy Valentine’s Day campaign that includes a special piece of bling—the Upside Down Heart Pendant, which women can treat themselves to while buying SAXX underwear for their man. 

The necklace is hand-crafted 14-karat gold “cradling two radiant, natural round-cut diamonds” with one carat total weight, the brand says—an impressive tribute in jewelry to the family jewels.

The campaign is from agency Quality Meats. This video explains more:

Befitting its premium crafting, the Upside Down Heart Pendant is available at SAXX.com for $5,000 while supplies last. It comes with a set of SAXX underwear for him—and Hanky Panky underwear for her, in a new partnership with the lingerie brand.

“We wanted to offer something special to those who offer their gentleman’s balls a little something special,” said Shawna Olsten, VP of brand marketing at SAXX. “And what better reward for valuing ballcare than a luxurious diamond necklace in the shape of a heart that happens to be upside down?”

Quality Meats has been creating amusing work for SAXX for a while, much of it ball-themed. Most recently, it created a “Ballgorithm” sabermetric stat to give balls respect in the World Series. It also bought Walter White’s old tighty-whities from “Breaking Bad” last year and blew them to smithereens.
