Oh, how intriguing this wallet is to my child!
When he could pull himself up he would dig through my purse, pull it out and take out whatever he could get to (yikes!). After upgrading to something a little more attractive, I decided to let him have it. Inside I put old gift cards and a few infrequently used reward cards and let him have at it.
I set it out, closed, on the carpet in invitation, and he runs right over to it and unsnaps the flap:

He will come back later for another one. It keeps him occupied for a few minutes and works those fine motor skills.
