The Professional Acrylic Modeler | 100% Natural Kolinsky

The Roubloff AK13R is a high-performance round brush specifically engineered for acrylic modeling and sculpting. Unlike brushes designed for gel, this series is made from 100% natural Kolinsky hair, which is considered the gold standard for acrylic work due to its superior liquid absorption and ability to maintain a sharp, fine point.

Key Product Highlights

Professional Grade: Specifically designed for nail technicians who specialize in acrylic modeling.
100% Kolinsky Hair: Features natural bristles that offer a full "belly" to hold monomer and a needle-sharp tip for precise bead placement.
Shape: Designed with a round ferrule and a tapered point, allowing the artist to switch between broad sculpting and fine detail work effortlessly.
Birch Handle: Features a lightweight, hand-treated birchwood handle for balanced control and comfort during long services.
Hand-Assembled: Each brush is balanced and assembled by hand to ensure professional-level durability and performance.

Size Guide & Use Cases

The AK13R series is available in various sizes to suit different modeling styles and nail lengths:

Size	Primary Use Case
#4	Ideal for smaller nails, intricate 3D acrylic art, or precise repairs near the cuticle.
#5	A versatile mid-size brush for standard nail extensions and medium-sized bead control.
#7	A larger professional size for faster application and sculpting long extensions.
#8	The largest in this specific range, designed for high-speed salon work and large bead placement.

Why Kolinsky is Essential for Acrylic

The AK13R's use of natural hair is critical for the chemical process of acrylic:

Monomer Retention: The natural scales of Kolinsky hair hold the perfect amount of monomer, preventing the acrylic bead from becoming too dry or too runny.
Fine Point Precision: Despite having a full "belly" for product storage, the brush can be drawn into an extremely fine point for detailing.
Durability: High-quality Kolinsky hair is resistant to the harsh chemicals in acrylic systems, maintaining its elasticity and shape longer than synthetic alternatives.

Care and Maintenance

To preserve the life of your natural Kolinsky AK13R brush:

Monomer Only: Clean the brush only in fresh monomer during and after use; never use acetone or brush cleaners, as they strip the natural oils from the hair.
Point Shaping: Always smooth the bristles into a sharp point before storing.
Proper Storage: Store horizontally or tip-down (if in a specialized holder) to prevent monomer from seeping into the ferrule, which can weaken the glue.
