Metra 4-Piece Scratch Brush Pen Set

The Metra 4-Piece Scratch Brush Pen Set is a compact cleaning kit containing four distinct pens: fiberglass, brass, steel, and nylon. It is designed for detailed cleaning, polishing, and rust removal on delicate items such as jewelry, watches, coins, and circuit boards. The pen-shaped bodies provide precise handling for intricate work. A storage bag keeps the tools organised and protected.

Adjustable Tip Replaces Fixed Brushes

Each pen features a twistable end cap that adjusts bristle length and hardness, replacing the need for multiple fixed-stiffness brushes. This mechanism lets you switch between gentle polishing and aggressive scratch or rust removal on the same tool. The jump is worth it when you regularly work on varied materials requiring different abrasion levels. The compact 17 x 11 x 2 cm kit consolidates a full range of abrasives into one portable package.

Suits Hobbyists and Precision Technicians

This set suits jewellers, watchmakers, electronics technicians, and automotive detailers who need pinpoint control in tight spaces. The nylon tip handles ultra-delicate surfaces while the steel and fiberglass pens tackle heavier oxidation. Buyers who require high-volume material removal or powered rotary tools should look at something else. The manual pen format is not built for large surface areas or continuous heavy-duty shop use.

Questions about this item

What are the overall dimensions of the 4-piece scratch brush pen set?

The set measures 17 cm in length, 11 cm in width and 2 cm in height, making it compact enough for a toolbox or workbench drawer.

How do I extend or retract the bristles on each pen, and what is the common mistake to avoid?

Twist the end cap to adjust the tip length and hardness; the step people get wrong is forcing the cap instead of turning it gently, which can strip the threads.

When will the four different tips — fiberglass, brass, steel and nylon — need to be replaced?

Replace a tip when its bristles become worn, flattened or clogged with debris so that it no longer cleans effectively; each material wears at a different rate depending on the task.
