Mont Marte Round Signature Waterbrush Set allows you to express yourself artistically. The brush set comes with three different-sized tips: a fine 3 mm tip, a medium 4 mm tip, and a broad 5 mm tip. The pressure-sensitive barrel and the durable Taklon bristles allow for delicate brushwork and control the flow of water. They work well with watercolors, inks, and other water-based paints.
