This is a DIY 3D wooden puzzle model kit from Robotime, designed to be assembled into a festive Christmas Melody Tree. It contains 319 pieces, and once completed, the tree rotates and is adorned with lights and ornaments.
The model functions as a mechanical music box, playing four classic Christmas tunes, including "Deck the Halls" and "Jingle Bells," when wound up.
The wide base of the tree features a detailed Christmas Village scene with a colorful choo-choo train circling snow-covered houses.
It is intended for teenagers and adults aged 14 and up and serves as a unique holiday ornament or a thoughtful Christmas gift.
