Handwritten mathematical formulas and equations densely cover a deep navy ground, their white chalk-like markings creating an intricate, layered texture across the entire composition. The effect is contemplative and intellectual, evoking the visual language of a blackboard or scholar's workspace where complex thinking unfolds. 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.
