The Official LEGO balls are hard to find these days as they are no longer produced by Lego group. That’s why they are really expensive nowadays! But we have the solution!
We have developed our own LEGO GBC ball packs which meet the LEGO GBC requirements and are guaranteed to work with all our GBCs.
For every LEGO GBC Module of ours you need approximately 1 pack of 50 LEGO GBC balls to make the ball flow go consistent and smooth looking.
The LEGO GBC balls are available in the colors White and Orange.
