A sealed box keeps its value and appeal only if it stays in good shape. These tips apply to Naruto Kayou boxes and most other trading card products.
Sealed boxes
- Store upright or flat on a shelf, away from direct sunlight
- Keep them in a dry room. Avoid basements and attics, where humidity and temperature swing
- Do not stack heavy items on top
- Keep the box in a clear display case or plastic box to protect corners
Single cards
- Put cards in soft sleeves, then a rigid top loader for valuable ones
- Store sleeved cards upright in a box, not loose in a drawer
- Handle cards by the edges
Near mint condition
Near mint (NM) means a card with no visible bends and only very light wear. Sleeving a card from the moment you pull it is the best way to keep it that way.
