They are perfect for teens who get money. My two elderly nieces aged 12 and 14 got things done quickly (5-10 minutes). It took my nephew 10 years old 10-20 minutes to figure it out and my youngest niece 8 years old couldn't figure it out but didn't bother much either because her older sister offered to open it for her . Which I think was a win-win because the younger sister didn't feel left out by getting something different and the older sister was able to show how smart she was by revealing it to her. So it worked. My nephew got a little upset and tried to take the scissors which was good it's his property now but I pointed out to him it was just money that couldn't be spent at the moment so there was no reason , why it should be open now, and that I will make sure it is open before he leaves for the night. Like brothers. At some point, however, he understood. I made sure they worked and put money in them instead of trying to use the slot at the top. The youngest liked to take it to school to show her friends and see if they could understand.
