The unglamorous but essential bits of Lego required to hold many of the more glamorous pieces together.
I don't know the names of the various connector bits , but hopefully you can recognise them from the photos.
The numbers on the paper beneath each part represent the number of that part.
The second part of the lot are a quantity of black axles of different lengths.
The numbers are -
Length Number
12 7
10 6
8 12
6 15
4 23
2 7
