We created our Sidekick 100+ in an exclusive extra-large version that holds 100 regular double-sleeved cards and has extra space for additional tokens, or it fits perfectly a Commander Deck in thicker inner sleeves.The Convertible line is designed to present cards in new and unique ways. Remove the lid, attach it to the bottom or start tilting your box in a wide variety of ways. Powerful magnets keep it safely closed.
