Here you'll primarily find brushes with water tanks. The brilliant thing about these is how easy it is to always have them in your pencil case. Or lie in a hammock and paint a little when the mood strikes.
We have three different brands in our assortment. Creotime is a budget option that actually works really well. Tombow and ZIG Kuretake are both Japanese brands that produce good pens or paints. It's probably six of one, half a dozen of the other which one you choose, as both are very good. Tombow is available in three different models and is also sold individually. ZIG Kuretake comes in a pack with four different models, and in our assortment, only the pack is available.
