Educational toy "Quadrilla" by BorneLund "Sound Rail set" [Special Notes] ◉ All parts are included. ◉ I have purchased additional marbles, so there are over 50. Instruction manual and outer box (damaged) are all included. ◉ Please understand that the uneven wood grain and color variations are due to the natural materials. As this is a used toy, please refrain from purchasing if you are concerned about minor details. * The outer box will be wrapped in cushioning material, and a shipping label will be attached for shipping.
