One of the most common mistakes collectors make is assuming that shrink wrap means “brand new.” Many retro game stores re-wrap opened games before placing them on display. That plastic may look convincing, but it is not the same as a factory seal.
When we buy large collections at The Old School Game Vault, we often see shrink-wrapped games mixed in. Some are legitimately sealed. Others have been re-shrunk. Here is exactly how to tell the difference.
Understanding Y-Folds
Disc games from major companies like Sony, Microsoft, and Nintendo feature a distinctive Y-Fold at all four corners if they are factory sealed. This folding pattern, cannot be mimicked by standard shrink-wrap machines.
Below is an example of a Brand New PS1 game, Tomba 2, compared to a PS1 Game that was re-shrunk, Intelligent Qube.
What we are looking at here are the corners I have circled – in the Tomba game, you see what I mean by the Y-Folds, and the Intelligent Qube game doesn’t have them. 
The Tomba game has a hole punched through the side of the game, I get games with a hole like this or a hole punch in the UPC code.. My understanding is that this was done to prevent returns, meaning that if an employee of Sony got this game brand new, they couldn’t take it to Best Buy to try to return it.
Understanding H-Seams
This is another shrink-wrap folding pattern used by Nintendo for their cartridge games over the years. An H-Seam is exactly what the name suggests: a seam running across the back center of the cartridge box, connecting to seams on the sides. When you look at the back of the box, the wrap forms an ‘H’—two lines on the sides and one seam down the middle.
In another example shown in the video below. I have a brand-new H-Seam Sealed copy of Shatterhand for the Nintendo NES. Then the comparison game is a Tang Tang, a Re-shrunk game from the Game Boy Advance library. The games are from different libraries, but Nintendo was consistent at folding their cartridge games with an H-Fold.
Final Thoughts:
When it comes to sealed games, the details matter. A true factory seal is not random plastic. Disc-based games from companies like Sony and Microsoft should show proper Y-folds at the corners. Nintendo’s cartridge-era titles should display a clean H-seam across the back of the box.
Once you understand Y-folds and H-seams, you can quickly evaluate listings, photos, and in-person copies without guessing. These small manufacturing details separate genuine factory-sealed games from re-shrink-wrapped copies.
