You can store your cards however you would like! There are limitless ways. I have a lot of cards (I stopped counting, I think I have around 500 decks now), so I needed a storage solution that could handle that quantity and weight. I couldn't find anything, so I made what I needed instead.
This box hold close to 600 decks of cards. It looks like you open it from the front, but it secretly opens from the top/side.
This is not a solution for everyone. I was OK investing the cash for this build (it was not cheap). I had enough cards to justify it. I already had an interest in woodwork (plus a woodworking father who had the tools and experience to help). I also had my own unique idea to create a "trick" box that would mess with people I showed it to. Unless you are a pretty hardcore card collector, something like this isn't for you. You may want to get something more along
these lines (this is where I started). A shoebox or dresser drawer may be better for you. I have seen kitchen drawers full of cards, unused cabinets, stacks of cards on a deck, and just about everything in between. There are a ton of options, just fine the one that is right for you.
