If you ever stepped on one of your kid’s toy cars you are going to need this. Keep your kid’s metal car organized (and out of the way) by using magnet knife holders.
There’s something even worse than stepping on a toy car: stepping on a lego. This can be solved if you use a shoe organizer to put the legos in. Of course that the legos won’t organize by themselves and you may step them on them once or twice. A day.
