A kit with a magnet theme that allows you to enjoy over 20 experiments. Includes a guidebook. I opened it and performed all the experiments. All the necessary equipment for the experiments is included, but please note that the stickers and cardboard sheets to be attached to the magnets have already been attached to the magnets or cut out. (In other words, it's ready to use.) Also, the mystery sheet and cardboard have slight creases. Please check the photos for details. (I think there will be no problem with the experiments.) - Brand: Gakken - Product Name: N-S Experiment Magnet - Number of Experiments: 20 or more - Target Age: 5 years old and up - Contents: Set of experiment equipment - Theme: Magnets and Experiments Thank you for viewing.
