Review on Experience The Thrill With ROKR Marble Explorer Wooden 3D Puzzle Roller Coaster Kit - 260PCS DIY Mechanical Model Educational Toy For All Ages! by Daniel Mind

I USED THIS AS TIME EATER DURING THE COVID. TOOK ABOUT 10 HOURS. TAKE YOUR TIME, IT'S NOT A RACE. THESE ARE HIGHLY ACCURATE LASER CUT PIECES. THE PIECES COME OUT OF THE SHEET EASLY. THE WOOD IS 1/8" PLYWOOD THAT IS VERY STRONG. I GLUED MANY OF THE PIECES TOGETHER TO ADD A LITTLE WEIGHT AND RIGIDITY ALTHOUGH IT'S NOT REQUIRED. IF YOU GLUE, MAKE SURE YOU YOU DON'T GLUE PARTS THAT NEED TO ROTATE. ALSO MAKE SURE YOU FULLY ENGAGE THE SLOTS COMPLETELY. OF COURSE " MADE IN CHINA".TWEEZERS AND EXACTO KNIFE ALL COME IN HANDY.
