Dark purple = cold / Light purple = hot

Thermal polish with violet shift and matte black glitter.

Care: Thermal polish will actively transition for up to two years if kept in a dark and cool environment. Once the polish is not able to transition anymore the color will remain in either the hot or the cold state.

We suggest using a base coat and 2-3 coats of polish followed by a top coat. 10-free. Vegan. Cruelty-free. Nontoxic.

This polish comes with a removable handmade decorative bronze cap atop our standard black matte nail polish cap - merging artistry with function. To forego bronze caps on your order, click here.

Lily ★★★★★

The color shift is so satisfying—I keep holding my nails under warm water just to watch them change. That dark purple-to-light purple transition is really dramatic with the matte black glitter catching the light.

Andrew ★★★★★

I was worried the thermal effect would fade quickly, but after a month it still shifts perfectly from deep plum to that bright lavender when I step outside. The matte black glitter gives it a cool edgy look without being too flashy.

Amelia P. ★★★★★

The color shift is so satisfying—I keep running my nails under cold water just to watch them turn dark purple. The matte black glitter catches the light perfectly against the violet base.
