Shop the Ultimate Selection of Marker Refills
Marker Refills are designed to match the tool you're using. In valve-action (or Pump Action) markers, the paint needs the right density to activate with nib pressure, giving you sharp lines and total control. On the flip side, with Mops and Squeeze Markers, fluidity is everything: here the refill must flow freely to create long, saturated drips with just a light squeeze of the soft body. Picking the right refill for empty markers based on whether you pump or squeeze is the key to turning your Empty Markers into precision instruments that perform perfectly on any surface.
Marker Refills: Ink or Paint?
The main difference lies in the formula and the final look. Graffiti ink is dye-based, designed to soak deep into porous surfaces for maximum staying power, making it incredibly hard to remove. It’s the go-to for Ink Markers when speed and buff-resistance are what matters most. On the other hand, paint marker refill uses pigments that sit on top of the surface to create a solid layer. Paint Markers rely on this to deliver opaque, bright colors that can be layered, perfect for cleaner styles or pieces where you need a bold, solid finish.
Marker Refills from Grog
Grog Refills hit two main targets: total coverage and extreme buff-resistance. The Grog Full Metal Paint 200 is a thick, high-pigment enamel that knocks out dark backgrounds with a solid, glossy finish. For an indelible mark, the ultimate permanent ink refill is the Grog Buff Proof Ink 200. This ink penetrates deep enough to create a "bleeding" effect, ghosting back to the surface even when painted over. Another standout is the Grog Mercury Chrome Paint Line, an alcohol-based formula delivering a killer mirror chrome effect on smooth surfaces.
Marker Refills for Squeezer® & Mops
With Squeezer® and Mops, getting the flow right is everything. The best ink for squeeze markers has to saturate the nib instantly for those juicy tags, but hold back enough so it doesn't leak all over your pocket. A proper Squeezer® marker refill should only flow when you actually squeeze the soft body. For heavy coverage, you've got paints like Grog Full Metal Paint 200, built for a thick, glossy finish. On the other hand, legends like Nero D'Inferno Nuovo Nero D'Inferno 250 ml set the bar for mop marker ink: a deep, penetrating black that keeps feeding the nib for long, continuous drips.
Marker Refills: Alcohol-Based
Alcohol-based refills are standard issue for speed and nasty drips. With a super-fluid solvent base, these inks run fast for bold lines and soak into the surface in seconds. A proper staining ink refill often packs extra additives to bite into the material, digging deep and making buffing a nightmare. However, achieving a flawless mirror finish paint requires a different technical approach: products like the Grog Mercury Chrome Paint 100 use specialized slow-evaporating solvents. This controlled drying time allows metallic pigments to perfectly align on the surface, creating a level of reflection and shine that fast-drying formulas simply cannot match.
Marker Refills: Water-Based
Don't sleep on water-based refills. Modern water based paint refill formulas pack serious opacity and durability that rival solvents, minus the toxic smell, so you can rock them indoors too. Usually acrylic, these paints are perfect for custom mixing: you can blend your own custom marker ink shades without worrying about clumping or weird reactions. The Molotow ONE4ALL 30 ml is the undisputed king here: crazy high pigmentation, dilutable with water or acetone, and versatile enough for technical markers or airbrush work.
