Many Luigi hats use adjustable snapback closures and are listed as one-size/OSFM. Knit beanies are generally pull-on (one-size); a noted 2-pack specifies a one-size fit for ages 14 and up.
Many items list machine wash and tumble dry care. One specific item (the green beret) instructs hand wash cold and lay flat to dry.
Features include reversible designs, removable rubber charms, breakaway closures for safety, and lobster-claw or metal clasp attachments. Wristlet straps often add a keyring and a detachable buckle for hands-free carrying.
Backpacks are described with a nylon shell and structured build, a zippered main compartment, adjustable shoulder straps, and interior laptop pockets. Some also include a molded rubber zipper pull or decorative charm.
Some Luigi accessories include age guidance: one beanie set is specified for ages 14 and up, and the backpack lists 3 years and up. Several other items use apparel sizing (for example, 'Sizing: Mens') rather than a specific age range.
