Born in Medellín, Colombia, Proton Professional Stencil Primer was created by a group of passionate tattoo artists who sought to solve a common industry issue stencil designs fading or wiping off during sessions. After extensive testing on thousands of clients, Proton was born: the strongest, longest-lasting stencil gel available. Its unique wax-like texture transforms into a smooth, fast-spreading blue gel upon application. This advanced formula ensures your stencil adheres instantly and stays in place for over 15 hours — no smudging, no fading, and no unwanted ink bleed. Now manufactured in Spain under the highest hygiene and safety standards, Proton retains its original Colombian formulation and uses premium-grade ingredients to deliver ultra-sharp, detailed, and clean tattoo transfers every time.
