A cream-colored echidna faces forward with its distinctive spiky quills fanned upward in shades of golden brown and tan, against a soft sage green background. The illustration employs a geometric, modernist approach with clean lines and flat color fields, capturing the animal's round body and alert expression with minimal but expressive detail. 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.
