We love our GBC Ferris Wheel. Don’t you?!

September 1, 2022 August 29, 2022

Monique Simon from Luxembourg built our GBC 38 Funky Ferris Wheel including our GBC Funnel Turbo Spin and Xylophone Keys. How fun to watch.
Insider news. We also have this GBC setup into our office as it is a great crowd pleaser :)

Have you also build one of our models yourself?
