The Treasurehive 90+ is specially designed to hold magnetic card cases, but it is perfectly suited to hold toploaders, standard sleeved cards, or Ultimate Guard’s beloved Boulder line as well. Ultimate Guard is excited to bring a deck box that offers archival storage for magnetic card cases, as there are currently not a lot of storage options out there. Many collectors still have tens of thousands of dollars sitting in carboard boxes. If you have a massive investment like that, you are going to want to display it and then put it away for safe keeping in something that makes the collection truly seem and feel like a treasure.
