QoR Mini Watercolor 12-Color Half Pan SetThe QoR Mini Watercolor Set houses 12 half pan watercolors in a tin smaller than an index card. It fits perfectly in pocket or purse for urban sketching and plein air painting. QoR (pronounced core) watercolors feature Aquazol, an advanced water soluble binder that allows for greater pigment loading than traditional watercolor binders, resulting in vivid depth of color in every brushstroke, while retaining the versatility of traditional watercolors.
