Mack Pinstripe Brush Set 10‑Series — Sizes 0, 00 & 000, Hand‑Shaped 100% Blue Squirrel

MACK Sword 10-Series Pinstripe Brush Set is a trio of handcrafted blue-squirrel hair stripers (sizes 0, 00, 000) designed for precise, consistent pinstriping and fine line work.

If you paint fine lines, lettering, or decorative pinstripes, the MACK Sword 10-Series set provides three graduated brush widths built for control and paint retention. Each brush in this set is hand-shaped from 100% unmixed blue squirrel hair and fitted with the brand’s distinctive blue thread ferrule. The regular hair length and careful finishing produce smooth paint release and reliable stroke memory—useful whether you’re restoring classic vehicles, adding accents to custom projects, or working on sign lettering.

How do these brushes deliver precise pinstripes?

The construction and hair selection are tuned for steady, consistent lines. Blue squirrel hair naturally holds pigment and releases it evenly, while the hand shaping and quality control ensure tips that run true without splaying.

• 100% unmixed blue squirrel hair for even paint load and release
• Hand-shaped tips for uniform stroke ends and minimized split hairs
• Regular 2" (5.08 cm) hair length for balance between flex and control
• Blue thread ferrule secures the hair and adds durability

Which brush sizes are included and when should I use each?

This set contains sizes 0, 00, and 000 to cover a range of fine-line tasks. The smallest handles the thinnest accent lines; the mid size suits medium stripes and script detailing; the largest creates bolder pinstripes and filler lines without losing a sharp edge.

• Size 000 (head width 1/4" / 6.35 mm) — for slightly broader decorative lines
• Size 00 (head width 7/32" / 5.55 mm) — versatile for medium accents and script
• Size 0 (head width 3/16" / 4.95 mm) — best for very fine single-stroke lines

What makes the 10-Series different from other pinstripe brushes?

The 10-Series emphasizes traditional handcrafting, premium animal hair, and focused quality control. Rather than mass-assembled heads, each brush is finished to preserve the natural qualities of blue squirrel hair so experienced stripers get predictable results stroke after stroke.

• Handcrafted and individually shaped like historic striping brushes
• Extra inspection for shape and cleanliness to reduce defects
• Choice of finest-grade blue squirrel for superior paint behavior
• Available in a full family of sizes (000 to 4) for matching multiple needs

How should I care for these brushes to extend life and performance?

Gentle handling and appropriate cleaning preserve tip shape and hair integrity. After each session, flush paint out with the recommended solvent or soap and water depending on paint type, reshape the tip with your fingers, and store brushes lying flat or tip-up to avoid deformation.

• Clean promptly with compatible solvent or mild soap and water
• Reshape tip by hand while damp; avoid crushing or bending hairs
• Store horizontally or bristle-up to protect the tip shape
• Avoid prolonged soaking or high heat which can damage hair and ferrule

Who is this for: The MACK Sword 10-Series pinstripe set is aimed at professional stripers, restoration shops, custom painters, and hobbyists who demand old-school craftsmanship with modern consistency. If you require dependable line control, long working paint hold, and hand-shaped tips in sizes for detailed to slightly bolder striping, this set covers common pinstriping tasks without synthetic compromise.
