Park kicked off the wire manicure trend — nails that use tiny pieces of bent wire to create images and accents — back in 2017. In an interview with Marie Claire, Park said the look was inspired by neon signs. "When you make neon signs, you have to bend the wires to make certain lettering," she told the brand. "It's one long wire that's bent to create and connect the letters. I thought this was really cool and since nails are an accessory, I wanted it to be used for expression. Like rings."
