Simbrix box divider / organizer

My then two and a half years old loves this building blocks, but she was struggling a bit while choosing colours (there are lots of colours available!).

So, taking advantage of the Simbrix box design I draw this tabs to serve as an organizer / separator for the colours as you can see in the picture.
