Frequently Asked Questions
Will the ink hold up if my outdoor signs get caught in the rain?
Yes. The alcohol-based permanent ink is waterproof and weather-resistant, so labels on fence posts, garden markers and equipment tags stay legible through rain, morning dew and humid conditions.
Can I use this marker to label camping gear and coolers without it rubbing off?
Absolutely. The quick-dry permanent formula bonds to plastic, metal and coated surfaces, so cooler handles, camp chairs and storage bins stay marked even with regular handling.
Is the chisel tip big enough to read trail markers and property signs from a distance?
Yes, the 15.88mm jumbo chisel point produces thick, broad strokes that are visible from across a yard, driveway or short trail, which is exactly why contractors and outdoor crews choose it.
Will the marker crack or leak if I leave it in my truck or job box overnight?
The rugged aluminum barrel is built to handle temperature swings, drops and tool box storage, so it holds up to overnight cold or summer heat far better than standard plastic-body markers.
Does the ink fade in direct sunlight on patio or signage projects?
The fade-resistant black ink is designed for permanent marking, so outdoor signage, patio labels and property tags stay dark and readable even with regular sun exposure.
Is this a good marker for writing on lumber stacked outside at a yard?
Yes, contractors and lumber yard staff routinely use the Sharpie Magnum to mark cuts, grades and dimensions on plywood, dimensional lumber and treated posts, and the ink holds up to handling and weather.
Can I label my kids' outdoor toys, bikes and sports equipment with this?
You can, and the permanent black ink works well on plastic, metal and rubber surfaces like helmets, bikes and bins, though because it is permanent we recommend testing a small area first.
Is the marker easy to carry on a hike or to a remote campsite?
The aluminum barrel is durable enough for pocket, pack or belt loop carry, and the secure cap prevents the marker from drying out between trips.
How does this compare to a regular Sharpie for outdoor property labeling?
The Magnum uses the same trusted permanent ink formula but delivers it through a 15.88mm chisel tip, so you get the same fade and water resistance on much larger, more visible strokes than a standard fine-point Sharpie can produce.
What is the difference between this and a paint pen for outdoor use?
Paint pens offer extra durability on slick surfaces, but they require shaking, priming and longer dry times. The Magnum is ready to mark instantly, dries in seconds and is far more convenient for quick outdoor labels and signs.
Will the marker dry out if the cap falls off in my toolbox?
The cap is designed to seal tightly, but like any alcohol-based marker, leaving the cap off for extended periods will shorten its life. We recommend keeping the spare marker from the two-pack in reserve for exactly that reason.
Is the ink safe to use around my garden and plants?
The permanent ink is intended for non-porous surfaces like plastic, metal, glass and finished wood, and it is not formulated as a garden marker for plant tissue. For pots, stakes and garden labels it works very well, but avoid applying it directly to living plants.
How do I get the best bold line out of the chisel tip?
Hold the marker so the wide edge of the chisel tip is fully in contact with the surface and draw slowly. Pressing harder does not make the line thicker, but it can shorten marker life and cause skipping.
Can I write on wet or oily surfaces with this marker?
The ink is waterproof once dry, but for best results wipe the surface clean and dry first so the ink can bond properly. Marking through standing water or heavy oil will reduce adhesion.
How should I store the marker so it does not dry out?
Always recap the marker firmly after use and store it horizontally if possible. Avoid leaving it in direct summer sun or in a freezing vehicle for extended periods, as extreme temperatures shorten ink life.
Does this marker work on glass, metal and plastic?
Yes, the permanent ink bonds well to non-porous surfaces including glass, metal, plastic, finished wood, coated cardboard and most laminates, which is why it is so widely used in warehouses and on job sites.
Can I use it on fabric or clothing?
It can mark fabric, but the ink is designed to be permanent, so it will not wash out of most textiles. We recommend testing a hidden seam first if you decide to label clothing.
What is included in the box?
The package includes two Sharpie Magnum permanent markers in black with a 15.88mm chisel tip. No additional accessories are required, and the markers are ready to use straight out of the package.
How long does each marker typically last?
Lifespan depends on the surface and how heavily you press, but for typical jobsite, warehouse and DIY use each marker lasts through weeks of regular marking. The two-pack ensures a fresh backup is always available.
Is the ink truly permanent, or will it fade over time?
The black ink is fade-resistant and engineered for long-term permanence on labeled surfaces, which is why Sharpie is the trusted brand for shipping, inventory, signage and jobsite identification.
What is the difference between a permanent marker and a paint marker?
A permanent marker uses dye-based ink that absorbs into or bonds with porous and semi-porous surfaces, while a paint marker uses pigmented paint that sits on top of the surface. Permanent markers dry faster, are easier to use and are ideal for most labeling, signage and marking tasks.
