This is a bead coaster similar to Kumi Kumi Slope, allowing for a game like the Pythagoras Switch. The clear colors are beautiful. All parts are present, with no damage, and I believe the condition is good. You can assemble the structures shown in the instruction manual photos. How about it as a Christmas present or for a fun activity for parents and children during the winter break? ^_^ This set includes the case, contents, and instruction manual. As a bonus, I'll also include the marbles in the last photo. #KumiKumiSlope #Marbles #MarbleRun ========= A multi-colored plastic bead coaster with balls to stimulate creativity. - Product Name: Bead Coaster - Colors: Multi-color (red, blue, yellow, green, purple) - Material: Plastic - Accessories: Balls (white) - Brand Name: WTOR Thank you for looking.
