Interlocking isometric buildings rendered in crisp line work create an endless geometric tessellation across a cool gray ground. The white-lined structures, each topped with diagonal hatching, stack and interweave in three-dimensional perspective, forming a hypnotic pattern that suggests both urban architecture and optical illusion. 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.
