Wrappable! This item can be beautifully gift wrapped.

Engenius Contraption is an award-winning flat-pack marble run that you assemble yourself.

This simply brilliant marble run is made of plywood, with all the parts coming laser-cut in sheets - just follow the simple set of pictures to push-fit them together. With a build time of 1-2 hours, assemble the spiral run and zig-zag before adding the electric motor. The marbles are raised to the top of the lift, descending down the spiral then down the zig-zag track...then back up to the spiral to start again, in perpetual motion. Winner of Gift of the Year 2019, fun and extremely satisfying to build and mesmerising to watch.

Wicked Uncle is the 'bees knees'!

I wouldn't use anyone else now! I don't have small children and am not day to day close with the ones I buy for,so I have little or no idea what they are 'into'. Wicked Uncle ALWAYS has the quirky, unusual, fun gift that the is perfect for the eccentric auntie! There is a handy alert when a birthday is coming up, they know how old the child is because they update more efficiently than I do. Prices seem varied and reasonable and delivery is prompt. The children are always keen to open 'Aunty Cathy' presents, they get played with immediately and there's alway lots of laughter and shared enjoyment. I'm so grateful because you've made one part of my life far less stressful and time consuming!

Cathy 2 Sep 2025
