The FLUX FX.PUMP 300E is the customizable version of a true classic. This empty 30mm pump-valve marker is the ultimate choice for artists who want to create their own custom ink or paint blends. Whether you want to fill it with high-staining "buff-proof" ink, liquid chrome, or a specific shade of acrylic paint, the 300E provides the heavy-duty hardware you need.
The standout feature of the 300E is its bottom-refill system, making it one of the cleanest and easiest markers to top up on the fly.
Key Features
Easy Bottom Refill: Unlike standard markers that require you to remove the nib and valve, the 300E can be quickly refilled from the bottom, reducing mess and extending the life of the nib.
30mm Chisel Tip: Equipped with a durable 15mm wide tip that delivers consistent flow and sharp edges for calligraphy or broad tagging.
Precision Pump Valve: The high-quality internal valve gives you total control over how much liquid hits the tip—perfect for creating drips or keeping it clean.
Full Customization: Because it comes empty, you decide the opacity, color, and permanence of your marks.
Technical Specifications
Status: Empty (No ink included).
Refill Method: Bottom-loading (screw cap).
Compatibility: Works with most alcohol-based inks, water-based acrylics, and liquid paints.
Why choose the FX.PUMP 300E?
If you are serious about your tools, you know that "off-the-shelf" ink isn't always what a mission requires. The 300E allows you to play chemist. Mix your own colors or combine inks for extra staining power. The robust construction ensures it can handle thick paints and aggressive solvents alike, while the 15mm tip provides the iconic "fat" look that is a staple of the streets.
