From Ordinary to Out of This World

HoloFang X instantly changes the feeling of an ordinary Halloween look. Instead of relying on a basic costume accessory, the transparent mouthpiece activates with intense Micro-LED light, dimensional holographic fangs, projected facial energy and a free-space character effect that appears to emerge forward from the wearer. The result is designed to turn one simple moment into a dramatic transformation experience.

Awarded the 2026 Best Product Design Award and Scientific Innovation Award, Billhol® HoloFang X represents a new generation of interactive Halloween wearable technology. Its transparent crystal-style architecture combines a Micro-LED Matrix, Smart Optical Waveguide, Dynamic Metasurface Layer, Motion Sensors, Future Light-Field Module and an integrated Energy Core inside one futuristic transformation platform.

🎭 No Complicated Costume Setup? No Problem.

You do not need a full mask, complicated makeup or an oversized costume to create a dramatic Halloween transformation. HoloFang X is designed around the mouthpiece itself. Its transformation system combines the physical product with digital visual layers that respond around the wearer.

Layer 01 — Micro-LED Teeth creates the physical illuminated base.
Layer 02 — Holographic Fangs extends the transformation beyond the real mouthpiece.
Layer 03 — Free-Space Character creates the most dramatic layer — projecting demons, ghosts, creatures or other transformation effects forward into the surrounding space.

One HoloFang X platform is designed to support multiple visual identities, allowing the same mouthpiece to create completely different Halloween experiences.

One Mouthpiece. Ten Modes. Endless Transformations.

Smart App Sync. Infinite Dynamic Transformations.

One of the most powerful concepts behind Billhol® HoloFang X is its connected smart transformation system. Through the companion mobile experience, users can select transformation identities, manage character modes, adjust interactive triggers and synchronize visual and sound behavior.

Standby.
Energy Activated.
Full Transformation.

From subtle illumination to full Demon Mode, each transformation can feel different. Facial light, holographic fangs, forward character projection and synchronized sound effects are designed to work together in real time.

Transparent Crystal Design. Built for Immersive Wear.

HoloFang X is designed to look like a futuristic wearable device rather than a conventional dental appliance. Its high-transparency crystal-style shell reveals the internal optical structure, Micro-LED architecture and signature purple-blue energy system.

🎃 Bring the Transformation Into Every Halloween Moment

HoloFang X is designed for more than one type of Halloween setting. Take it into trick-or-treat nights, street parties, Halloween family gatherings, backyard haunts, costume events or other nighttime celebrations.

When activated, the mouthpiece becomes only the starting point. Light spreads through the product, visual energy appears across the face, dimensional fangs form around the mouth, and a character can appear to burst forward into the surrounding space.

The experience is designed to make the reactions of friends, family and everyone around you part of the transformation itself.

HoloFang X is envisioned as more than a one-night Halloween accessory. The mouthpiece, companion app, wireless charging case and digital Character Library form one connected future ecosystem.

Wireless Charging keeps the mouthpiece ready between transformations.

Smart Sync connects modes, triggers and interactive settings.

Character Library allows the hardware to support multiple digital identities, including Demon, Vampire, Frost and future transformation packs.

The charging case concept can even display a dimensional holographic character preview above the dock.
