Lego - various search bin

These are used all the time at home.
We have lots of lego, assorted in a lot of tipping boxes. Problem with these tipping boxes is that searching in them is difficult since they`re too deep wrt top opening.

With tis, you can throw the content of a tipping box in this "search bin" which spreads it out and makes searching a lot faster.
When you find the part you can empty the content back in the tipping box within seconds.
