Online seal shop Hankos has started selling interchangeable heads for its officially licensed My Hero Academia Emblem Sealing Stamp, according to a PR TIMES release dated October 27, 2026. The shop is run by an Osaka-based company.
The original sealing stamp turns characters from the anime into crest-style emblems based on their Quirks and costumes. Owners can now swap in a different brass head. The release says the company made the heads in response to many customer requests.
There are 24 emblem designs. They cover U.A. High School students including Izuku Midoriya, Katsuki Bakugo, Ochaco Uraraka and Shoto Todoroki; pro heroes such as All Might, Shota Aizawa, Endeavor and Hawks; and villains including Tomura Shigaraki, Dabi and Himiko Toga. Each head has a brass stamp face 25 mm across. Buyers can get a single head or pick their own characters for a three-piece or five-piece set. The release does not list prices.
The heads are sold through the shop's Rakuten and Yahoo! Shopping storefronts. Hankos suggests using the wax seals on letters, gift wrapping, message cards, notebooks and handmade accessories. The product is meant for personal hobby use, though: the release says selling items stamped with the designs is strictly prohibited under contract.
