A sleek slate gray creme for modern manicures with matching gel and lacquer versatility.
✦ Modern Slate Color Pairing
DND HEMA & TPO Free Duo #257 Bad To The Bone brings together two coordinated nail color formats: one soak-off gel polish and one matching air-dry nail lacquer. Each bottle contains 0.5 fl oz / 15 mL, making it easy to create a cohesive shade story across gel manicures, classic lacquer applications, and pedicure services.
Bad To The Bone is described as a mid-tone slate gray creme, offering a polished neutral that feels clean, cool, and quietly bold. The gel formula is marketed by DND as HEMA & TPO Free, while the duo format gives professionals and at-home users the flexibility of matching color in both lamp-cured and air-dry finishes.
