Once a graded card collection grows past a handful of slabs, storage stops being optional. The question isn't whether to buy a dedicated box, it's which locking system actually fits how you travel and store.
EVORETRO's two top-selling graded storage options both use aluminum construction and multi-row layouts, but the lock type changes how each one is actually used day to day.
This guide breaks down the practical differences between the TSA-Lock Graded Card Storage Box and the Graded Case with Key System.
A TSA-approved lock is designed to be opened by airport security without being cut or damaged, which matters specifically if you're flying to a card show with slabs in checked or carry-on luggage.
Outside of travel, the TSA lock functions like any combination lock, quick to open repeatedly without needing a physical key that can be lost. That makes it a reasonable everyday option even if you never fly with it.
A key lock is simpler and, for many collectors, feels more secure than a combination, there's no code to forget or accidentally reset. The tradeoff is the obvious one: lose the key, and you're dealing with a locked box you can't easily open.
Key-system cases tend to appeal to collectors storing the box in one place long-term, a safe, a closet, rather than moving it around often, since the key can simply live in a fixed, secure spot.
Both formats come in multiple row counts, holding roughly 60 to 90 standard-size slabs depending on the configuration chosen. Neither format is meaningfully more space-efficient than the other, the real difference is entirely in the locking mechanism.
If your collection spans oversized slabs alongside standard ones, check row height specifications before buying either format, since oversized graded holders don't fit standard row dimensions.
Both formats typically use aluminum shells with foam-lined interiors, which matters for cushioning slabs against shock during handling or transport. Check the foam density and row spacing specifically, cheaper versions of both lock types sometimes cut costs on interior padding rather than the lock mechanism itself.
A well-built box in either lock style should feel solid when closed, with minimal flex in the shell and a latch that seats firmly. If a box feels flimsy at the latch, that's usually a better predictor of long-term durability than the lock type itself.
For a first dedicated graded storage box, think about how the collection will actually be used day to day rather than which lock sounds more secure in the abstract. Frequent travelers benefit more from the TSA lock's air-travel compatibility, while collectors storing a box in one fixed spot long-term often prefer the simplicity of a key.
Neither choice is a mistake, both are well-built, similarly priced options from the same product line, so this decision comes down to habits more than any meaningful protection gap between the two.
Both box styles come in multiple sizes, so it's worth buying slightly ahead of your current slab count rather than exactly matching it. A box that's already full the day it arrives means shopping for a second one sooner than you'd like.
If you expect your graded collection to grow substantially, consider starting with a mid-size box in either lock style rather than the smallest option, the price difference between sizes is usually smaller than the cost of buying a second box entirely.
Regardless of lock type, storing the box itself somewhere secure and out of direct sunlight matters just as much as the lock mechanism. A closet shelf or a small safe both work well, avoid leaving a valuable graded collection box visible in a main living area where it draws unnecessary attention.
Airport security has master tools to open TSA locks without damaging them, which is the entire point of the design.
You'll need a locksmith or a replacement lock mechanism, since there's no universal override like a TSA lock provides.
Capacity varies by the specific row configuration chosen, not by the lock type itself.
Either works, though a key-system case is a common preference for a fixed, long-term storage spot.
Both formats protect your collection equally well physically, the real decision is about how you'll actually access and transport the box. Pick based on your travel habits, not just row count or price.
