Geometric rectangles in primary colors and black form a balanced composition against a light ground, arranged with the careful restraint of neoplasticism. A small black square sits apart in the upper left, while bold planes of blue, red, and yellow stack and intersect below in clean, perpendicular lines. Sewn from a durable canvas-like exterior with a soft lining and made to order, in three sizes up to one that fits a tablet. A catchall for toiletries, art supplies, or small electronics, carrying an independent artist's work instead of a plain zip bag.
