Unbeatable for value. Many perform identically with "European" brands (also made in China) costing many times the price.
Their Hog bristle brushes are top notch. Their taklons are golden filamented synthetics with a lovely soft, smooth feel. Ideal for acrylics, gouache and watercolours, and can be used for oils especially thinned down).
Mont Marte's Oil Taklons are brushes with a bigger diameter synthetic filaments, meaning their bristles are a little stiffer than the Taklon, but not as stiff as Hog bristle. They are a sumptuous alternative to Hog bristle, and give a great feel to oil and acrylic painting.
Their Hake's and natural hair watercolour brushes are literally identical to many other traditional brands. You won't be disappointed. The Chinese have been making watercolour brushes for millennia.
