Mega boxes commonly focus on major sports such as baseball, basketball, and football, as shown in many product listings.

Large storage sets often include multiple storage boxes plus organizing accessories such as colored card dividers, label sheets, double-sided tape, self-adhesive dots, and an installation guide.
