Growth

Healthy, chip-free wear that lasts beautifully over time.

Customers say this sparkly polish catches the eye with its vibrant blue hue. Many note how it shifts colours in different lights, showing hints of green and purple. The glittery finish works well both alone and for layering. Several mention needing 2-3 coats for full coverage.
