Spiral Marble Run 3D Wooden Puzzles for Adults and Teens DIY Model Building Kits with Mechanical Puzzles 

Bit tricky to build but at the end it was worth while building it cause it was satisfying to watch it come up and down the track for the marble it is better than i thought it would be

every part there, the build itself was rough but worked well enough

haven't built it yet but it looks just like the picture

nice

same as original Service

AAA product and quality service 👌
