Lotte and Kodansha opened orders for more Koala’s March merchandise that features The Quintessential Quintuplets characters. Orders are open via the Lotte Online Shop official site in Japan until February 1, 2026. The items include images of the heroines dressed as koalas, as well as the cookie mascots dressed as each one of the sisters. The merchandise will ship in Japan at the end of March 2026. These follow past events where characters appeared on cookies in 2020, then on boxes in 2025.
There are four types of Koala’s March items based on The Quintessential Quintuplets. Most expensive are the t-shirts, available in L and XL adult sizes. These are ¥2,780 (~$17.60) each, and the design features the sister’s signature color, them with koala ears, and them as a Koala’s March mascot. The acrylic stands that feature them as humans and koalas are ¥1,380 (~$8.80) each. The acrylic keychain pairs are the same price. There are also sets of tin badges, which randomly gets you a pair of pins featuring one of the quintuplets and her koala form.
Here’s how all of those items look:




Since these are made to order direct from Lotte Online Shop, we probably won’t see them available via other retailers. Someone who wants one would need to use a proxy service or check online auctions. The past items did show up on eBay.
The manga is handled by Kodansha, and the anime is streaming on Crunchyroll.
