I have listed this 2017 set as used although none of the contents have ever been used. 30 Pieces for Ages 8+.\nCrafty DIY kids will love creating this robot family trio that really glow! This all-in-one science and craft kit comes with a plastic needle and pre-cut felt, making assembling your three robot plushies safe and easy.\n\nOnce the robots are put together, use the included LED lights, batteries, and conductive thread to complete the project. When they hold hands, they\u2019ll complete a circuit and glow with life!\n\nRobots are super cool, so what better way to teach kids the basics of sewing, as well as electricity and circuits? This kit makes STEAM learning exciting and fun; and the instructions make a seemingly complicated project easy to understand!
