Thank you for viewing. This item appears to be a manufacturer's product (https://toy.bandai.co.jp/series/rider/item/detail/13450/) with a custom-made blade. Due to the above, there are minor scratches and paint剥がれ (peeling). I have confirmed that the original sound function works by inserting a AAA battery. Please consider purchasing if there is interest. Size: Please refer to the comparison with a 2L plastic bottle. Material: The blade is made of plastic and putty. Swinging it around and hitting someone is very dangerous, so please handle it with extreme care. Condition: There are many scratches and wear due to age. Thank you.
