It’s like a wallet — if you open it one way, one set of straps should open— allowing you to place bills, receipts, etc under the straps. Then if you open it the other direction, the other set should lift, allowing you to put stuff under that side.
The pamphlet. It just reminded me of this wallet.
Remember this thing?
