My 7 year old absolutely loves these boxes. The quality is fantastic. The puzzles are really well thought out and clever. I wish you would make more of them because we've bought all 6 and want more. Each box takes her about 4-5 hours to figure out. They've been a lifesaver during this pandemic as a way to really get her to feel like she's having an experience. If you are sitting on the fence about these just do it. They made a fantastic Christmas gift as we're trying to focus less on stuff and more on activities. So good. Keep up the good work!!!
