ManaCore Lid
This lid is top-notch! Lid-erally! Whether you need a replacement, spare, or another color option,
we’ve got you—and your accessories—covered.
Magnets on the lid allow it to mate to other ManaMate products.
Designed Specifically for MTG Players
These deck boxes and accessories are calibrated around the physical standards of Magic: The Gathering cards.
Fit testing is performed using standard MTG dimensions (63 × 88 mm cards). Models are optimized for:
Single-sleeved decks
Double-sleeved decks
Inner + outer sleeve combinations
If you use thicker specialty sleeves, consult capacity specifications before ordering.
Structural Design Features
Magnetic closure for secure transport
Friction-fit lid tolerances tuned for repeat use
Clean internal cavity walls to prevent sleeve snagging
Every model is printed with structural integrity as a primary consideration, not just aesthetic appeal.
Care & Handling
To maximize product lifespan:
Avoid prolonged exposure above ~55–60°C (131–140°F)
Do not leave in hot vehicles
Clean with mild soap and water; avoid harsh solvents
Store in dry conditions
