The Pokemon PON stamp series has increased its lineup of available Pokemon. Consumers will be able to further customize their signatures with the latest batch of Pokemon PON stamps. However, signature customization only includes Japanese characters so there will be some limit as to what you can do. Pre-orders are currently open, with a total of three different stamp types available. [Thanks, Gamer!] The latest additions to this stamp series includes all 156 Pokemon from the Unova Region. Additionally, you can choose from Pokemon featured in the Kanto, Johto, Hoenn, and Sinnoh Regions as well. These Pokemon were made available in past years. As mentioned previously, three stamp types will be available to choose from. Each range in price depending on how many you order per set.
