Card storage boxes and carrying cases come in a wide range of sizes, from small boxes for 100–200 cards to large cases that hold over 2,000 cards. For B2B buyers, wholesale packaging is often optimized for different collector needs, such as single-deck boxes, graded card cases, or bulk storage trunks for shops. Businesses typically stock multiple sizes to cover retail demands, from casual players to serious collectors. Custom sizing is also available for distributors seeking unique market positioning.
