Layered bands of deep purple, indigo, and mauve flow across the composition like a natural geode cross-section, with shimmering gold and rose-gold glitter particles scattered along the undulating borders. The effect mimics the crystalline interior of agate, creating luminous striations that suggest both geological formation and ethereal movement. 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.
