Once you know what makes a retro game valuable, the next question is how to actually keep it that way. Here's a practical breakdown, format by format.
Keep cases and cartridges separate from daily handling
Every time a case is opened and closed, or a cartridge is inserted and removed, there's wear risk. If a game is staying in your collection long-term rather than getting played regularly, consider a second, playable copy for actual use and keep the collectible copy sealed in its protector.
UV light and humidity are the real long-term threats
Sunlight fades box art and yellows plastic over time — keep display shelving out of direct light where possible. Humidity swings warp cardboard boxes and can encourage mold on manuals; a stable, moderate environment matters more than any single storage product.
Match the protector to the format
Different eras and consoles used different box shapes and sizes, so a one-size-fits-all case doesn't really exist. We carry protectors sized for the major formats:
- PS1 / Dreamcast (jewel case format): PET protectors, pack of 25
- GameCube / Xbox 360 / Wii / PS2 / DVD-style cases: PET protectors, pack of 25
- Xbox One / PS3 / PS4: PET protectors, pack of 25
- NES-style boxes: Rigid acrylic protectors, pack of 2
- Larger/wide game boxes: Acrylic DVD-format protectors, pack of 2
PET (soft) vs. acrylic (rigid) — which to use
PET protectors are lighter, cheaper, and better suited to large collections you're storing on shelving. Rigid acrylic cases offer stronger physical protection and a premium look, and are generally the better choice for display pieces or graded/high-value items you're showing off rather than storing en masse.
Handling manuals and inserts
Paper inserts are often the most fragile part of a complete-in-box game. Avoid excessive flexing when removing them from a case, and consider archival sleeves for particularly valuable manuals separate from the case protector itself.
General preservation guidance based on standard archival practices for paper and plastic media; individual item condition and rarity should guide how much protection is worth investing in for any specific piece.
