Grumbacher's Academy line is ideal for the art student, offering near professional quality at a uniform and affordable price. Unlike many of the so-called "budget" brands, Grumbacher uses genuine and pure pigments, such as pure cadmiums, to produce Academy Acrylics. Hues are carefully formulated to provide authentic tints, and just the right masstones, undertones, and mixtures. Colors are lightfast, consistent, opaque, and demonstrate strong adhesion. Because Academy Acrylics are subjected to the same tough quality standards as Grumbacher's professional paints, colors are supremely consistent from batch to batch. This means that students can easily achieve the right color mixtures without frustration or waste. Individual tubes are 3 oz (90 ml).
