The Grafx Aqua Ink Pump Softliner is unlike any other marker on the market due to its combination of the water-based special ink and soft edge brush tip.
Due to its soft edge brush tip, it can be used as fine and wide nib all in one. Use the marker upright so that only the tip touches the paper for fine lines, and use it on an angle so that the entire nib is on the surface of the paper for a wider stroke, similar to a chisel tip
Once the nibs have been filled, the colours come out very dark, and after use without re pumping the nib the colour becomes lighter and lighter.
“Another great aspect of these is that for the time being they one of the only watercolor markers that is refillable and have interchangeable nibs. ”
