[All] G-Dragon 20p file purchased by my younger brother

This is a 20p G-Dragon file that I bought with points my younger sibling gave me at a shopping mall.

I want to take it apart and look inside, but they say they don't want to. What can I do?

It's a regular file the size of A4 paper and looks sturdy.

If you look closely, it doesn't look like G-Dragon's face, even though it's an old product.
