Where can I get these protective boxes?

I wanted to ask where I can get such protective boxes. If you could tell me, it would be best to use Amazon link

I need such cases for Nintendo Switch games or for a Nintendo Game watch I want to collect them

Thank you

These are sealed boxes. To do this, you send your games to VGA (or another organization) who will check whether your game is real, and then seal it. They can't be opened without destroying them.
If they would sell you the boxes, it would be easy to fake it.
