What binders were used for the Cisco's Who's Who? Binder from Arrowverse's The Flash TV series?

I was thinking from looking things up on the internet that it was either the Exceed heavy duty binder or the 3-Ring Better BInder from Staples. Was wondering if either one of them were used or another binder or if one of those two binders were used as the basis for the binder then modified.

I'm pretty certain it's the Better Binder from Staples.
