Before you buy
Questions? Answers.
Do I need glue or tools?
Our mechanical models, marble runs and music boxes fit together without glue, and no special tools are needed. Some miniature house and book nook kits use a little craft glue — any extras are listed in the product description.
Is this kit right for a beginner?
Check the difficulty and build time shown above. Beginner and Intermediate kits are perfect first builds; Advanced kits are for builders who want a real weekend project.
Does the model really move?
Most of our kits do — gears turn, wheels roll, marbles run or music plays, powered by rubber bands, wind-up springs or a hand crank. A few are display models that stay still. The description says exactly what moves on this kit.
What if a piece is missing or breaks?
Email us a photo and the part number. We ship a replacement free of charge.
Is it a good gift?
It’s one of our most gifted products. It arrives in its sturdy printed retail box — ready to wrap.
