Sharpie Magnum Permanent Marker Oversized Chisel Tip Blue - Bold

In this review the Sharpie Magnum Permanent Marker pack is recommended for anyone who needs bold, extra-wide marks that last. The pack of 12 oversized chisel-tip markers is built for poster boards, pallet marking and large-scale labeling where visibility matters, and the single biggest reason to buy is the extra-wide felt chisel tip that makes fast, legible strokes across large surfaces. The review looks at tip size, ink durability and ease of use to judge whether these markers perform as claimed.

Key Features

• Oversized body: The larger barrel offers a firmer grip for extended use and helps keep the marker steady when making wide, bold strokes.
• Extra-wide chisel tip: The large felt chisel creates clear, precise extra-wide marks ideal for poster boards and visible labels from a distance.
• Permanent blue ink: The intense blue is vivid and provides high contrast on light surfaces for easy reading.
• Quick-drying formula: Ink dries fast to reduce smudging on paper and poster board during rapid work sessions.
• Fade- and water-resistant: Marks persist outdoors and in storage so labels and posters remain readable over time.
• Pack of 12: Multiple markers in one pack offer value and spare tips for projects that need many large marks.

Who It's For

The Sharpie Magnum is best for teachers, event planners, sign makers and warehouse staff who need quick, bold labeling on poster board, corrugated cartons or shrink-wrapped pallets. Its oversized tip and body make it particularly useful when visibility from distance is important or when speed is required for marking many items.

Those who need fine detail or small writing should look elsewhere; the extra-wide chisel tip is not designed for precise, small lettering. If water immersion resistance is required, consider speciality permanent markers made for heavy exposure, since this product is described as water-resistant rather than fully waterproof.
