A densely branching neuron fills the composition with intricate black line work against a warm cream ground, its delicate dendrites spreading outward in organic, fractal-like patterns that suggest both botanical growth and electrical impulse. The scientific precision of the rendering conveys the wonder of neural architecture, capturing the microscopic complexity of the brain with the hand of a naturalist-anatomist. 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.
