This is a set of three items: the DX Megalodon By-Stamp, the DX Lion By-Stamp, and the DX Eagle By-Stamp. These items are also available for individual purchase, but this set is offered at a significant discount, so we encourage those interested to purchase early. Batteries must be purchased separately. We will offer further discounts for those who wish to purchase multiple items, so please leave a comment if you are interested. Thank you very much. Kamen Rider/Series: Kamen Rider Revice
