This is a stack of cards with symbols that you have to guess which one each attached to its own card in a headband on the head.
In addition to the cards and plastic headbands (which are much too far for a 7-year-old, even if the hole closes over the last) is listed an hourglass. That was it but also already.
Overall, this is all quite poor, actually, you can place the card itself also symbols on a sheet of paper or paint to a post-it note paperboard forehead. Especially as the kids quite a few cards quickly memorize.
The bottom line for me is: too expensive.
