A stylized Atlantic bluefin tuna swims across a deep cobalt ground, its muscular body rendered in shades of blue, yellow, and lime green with bold geometric patterning along its sides. The fish is captured in profile with an alert gaze and dynamic posture, its fins and tail alive with warm accent colors that suggest movement and vitality against the cool monochromatic background. Constructed from woven polyester with a soft microfiber lining and a sturdy zipper, made to order for 13 and 15 inch laptops. Everyday protection carrying an independent artist's work, not another plain black sleeve.
