F.O.X Builder gel Flashback 004 is a collection of light-reflecting builder gels that combine advanced technology, strength and eye-catching shine.

004 — a warm brown-bronze with a strong holographic shine.

The innovative formula contains micro-particles that scatter and reflect light on contact, creating a bright shine, shimmer and "diamond glow" effect.

• Eye-catching look — the gel gives nails a luxe shimmer, especially striking under flash or direct light; ideal for holiday, evening and fashion looks
• Versatile — works for strengthening natural nails or for extensions; can be used as a standalone coating or a base for further design
• Durable and reliable — a dense, wear-resistant formula for excellent longevity
