Although all batteries have been removed, I have confirmed that they work for the purpose of this listing. The main battery type is AAA, but the Mezamashi Korasho and Start Navi use AA batteries. Please prepare these yourself. There are many items, so I will only provide descriptions for the main ones. Please be sure to check the images, as I have included explanations there. Also, please check the box and instruction manual in the images. 【Tokei Master】 Kodomo Challenge Step Learn how to tell time. The sticker part is discolored. 【Kakijun Shiraberu Master】 Kodomo Challenge Jump Learn the stroke order of hiragana and katakana. There is no katakana sheet, but it switches to katakana by reacting to the paper protrusion, so you can use the katakana function by inserting any paper. 【Start Navi】 I have disposed of the QR code, so it has not been initialized. Please check the usable content in the images. It is valid until August. It also has a microphone, but the recorded voice seems difficult to understand. 【Mezamashi Korasho】 As shown in the image, Korasho's body is yellowed, possibly due to sun exposure. Please check the other items in the images. Items from Step to 2nd grade [Science and Experiment Kit] are mixed. Some DVDs are unused, while others have scratches from multiple viewings, but they are usable. Some booklets have tears and folds. I will ship them in the Korasho treasure box, but the address label is directly affixed and sent from Challenge, so it is not clean. Please consider it as a packing tool only.
