When Randi Johnson was undergoing treatment for breast cancer, her husband, Brian, often felt at a loss to help. But then, when he and Randi met with a surgeon to discuss reconstructing her breast, he was struck by something he could do. The Midwestern father of five, a lifelong tinkerer, decided to make his wife the best possible prosthetic nipple.

“The nipple solution is actually very elusive,” Randi said. “Surgical nipples tend to flatten. Tattoos fade. Or they still don't have dimension. The … prosthetic nipples that were around when we started, they looked really fake, and they'd fall off. And that's really kind of a deal breaker.”

After Brian made one for Randi, the two of them decided to offer the service to others. Today, they make affordable, realistic nipples for dozens of people a year, largely reaching potential customers through word of mouth.

One of their sons, Justin, recently chronicled their work in his new documentary “Mom & Dad’s Nipple Factory,” now available for rent or purchase on streaming platforms. (Watch the trailer here.)
