Product description

Cosmic Blue · 406 is a gel polish for those who love blue nails with vivid color intensity and a sophisticated look. The shade has a rich royal blue tone with a deep undertone, giving the manicure more dimension than a classic bright blue.

In natural light, the color can appear almost electric blue, creating a fresh and energetic effect. In artificial light, it becomes deeper and more intense, making the manicure feel both elegant and eye-catching. This makes Cosmic Blue ideal when you want nails that stand out while still looking polished.

The semi-transparent finish gives the color a lighter feel, while the pigmentation ensures a visible and vibrant result. Wear it on its own for a clean royal blue manicure, or combine it with nail art, glitter, chrome effects, or contrasting colors for a more personal design.

This gel polish from Nailster is a great choice when you want a shade that feels modern, bold, and wearable across seasons. It works beautifully on both short and long nails, as the vivid blue tone gives the manicure a sharp and clean look.

For the best result, Cosmic Blue must be cured under a UV/LED lamp for 60-90 seconds. Apply in thin layers to achieve an even surface and beautiful depth. Finish with your preferred top coat to seal the color and create your desired result.

Why choose Cosmic Blue · 406

• Beautiful depth in the finish: The semi-transparent formula makes the color vibrant and dimensional in different lighting.
• Great for both simple looks and nail art: Wear it on its own or use it as a base for creative nail designs.
