Andrew Mack & Son Brush

The Legacy Behind Every Stripe

Few names in the world of hand-applied finishing carry as much weight as Andrew Mack & Son Brush Company. Founded in 1891 in Jonesville, Michigan, the company's roots stretch even further back — to 1865, when J.J. Deal established a wagon and buggy factory whose dedication to flawless paintwork set the standard for craftsmanship in the Midwest. It was there that Andrew Mack, serving as head striper, grew frustrated with the limitations of available brushes and began experimenting to develop something better. The result was what became known as the Mack Striping Pencil — and the foundation for one of the most respected brush manufacturers in the world.

American-Made Craftsmanship Since 1891

What separates Mack brushes from virtually every competitor is an unwavering commitment to hand production. Every pinstriping brush is a completely hand-crafted operation — no machinery is involved in its manufacturing. Each brush is produced by a small team of skilled technicians right in Jonesville, Michigan. The squirrel hair used in Mack's iconic striping brushes is 100% unmixed, a claim no other pinstriping brush manufacturer can make. This level of material purity translates directly into the brush's legendary performance: smooth, consistent paint flow, precise tip control, and the kind of snap and memory that professionals rely on for flawless stripe work.

The company has been family-operated across multiple generations, guided by a philosophy that values customer feedback and continuous improvement. Over the decades, Mack has evolved from a single-focus striping brush maker into a diversified brush company serving artists, custom painters, sign painters, and automotive detailers worldwide — all while keeping the core manufacturing process exactly as Andrew Mack intended.

A Complete Range for Every Specialist

Today, Mack offers an extensive catalog of brush types designed for specific trades and techniques. Their pinstriping brushes remain the flagship line, with series like the Original Sword Striper (Series 20), the Long Stryper (Series 1111), and collaborations through the Signature Series that bring top artists' preferred designs to market. For the sign painting community, Mack produces lettering quills, scroll brushes, fitches, cutters, outliners, and highlighters — tools built for everything from hand-lettered signage to billboard backgrounds and vinyl banners. Specialty blends including golden taklon synthetics and European blue squirrel hair give professionals options to match the right brush to any medium or technique.

The Signature Series is particularly notable: it represents direct collaborations with leading artists and custom painters, incorporating real-world feedback into brush geometry, hair blend, and handle design. This tradition of listening to the people who use the tools most has kept Mack relevant and trusted through more than 130 years of industry change.
