"Onyx" Jet Black Creme Nail Polish - 10ml

Yes! Onyx is the black crème nail polish you will have on high rotation all year. It is ridiculously chic and has a super-inkey pigment for the jet-black nails of dreams.

A note from Sienna about this colour:

Due to not using nano-particles, Onyx may need 3 coats to achieve full coverage. A common ingredient used in darker colours is ‘nano-black’ code CI 77266 which is made up of nano-particles. This creates a more solid pigment however we feel it’s not worth the compromise to our health by using this ingredient. We hope you feel the same. xx

Sienna nail products are proudly & ethically made in France. Certified vegan, cruelty-free, breathable, and derived from natural ingredients: sugarcane, cassava, cotton and corn. Sienna's formula is a world first with no nano-particles, no benzophenone-1 and none of the standard toxic ingredients everyone says no to!
