JOLTONE

The Joystick DIRT Mop contains a hard staining heavy opacity ink. It comes in two sizes, a 10mm nib version that has 90ml of ink and a 25mm nib version that has 75 ml of ink.

The Joystick DIRT Mop comes in 5 colors: black, white, violet, blue and red. The mop also comes empty so you can fill them with your own ink and yes of course they are refillable. The nibs on the Joystick DIRT Mops are nylon to ensure optimum flow. The nibs can easily be replaced. The marker's body has clear plastic so you can keep track of how much in you have left.
The marker body is very soft allowing it to be squeezed easily to get nice drips or you can get a clean line by not squeezing it.
