I have put in a small pouch to hold my cellphone. And in the main space I can stuff in some money, my cards, hairbands, clips, my lipbalm, and a small notepad. I actually took out all these things in my purse last Sunday when we went out. I felt sooo happy!
Well, the button closes perfectly and doesn't let any of my cards or money slip out. The button and fastener keeps my cellphone in place and is easy to take out the phone quickly. You see, CONVENIENCE.
