Two-pack with empty pump markers from Molotow. The markers can be refilled with virtually all types of ink and are also suitable for liquid acrylic paint (e.g. Molotow ONE4ALL refills). The marker itself is made of transparent plastic so you can easily see what color you have and how much is left. In addition, both markers also have the Molotow Extension Ring which allows you to easily open the pen and refill without spilling. Molotow 224EM Empty Marker has a 1.5 mm and a 4 mm round tip that can also be replaced when they have dried or become too worn. You can find more markers, refills and more from Molotow here.
