Collaboration Details
"Waguma," which debuted as a character on O-Band's official Instagram in 2024, gradually gained popularity among followers and became O-Band's official mascot in 2025.
Previously, "Waguma" merchandise was only available through Instagram campaign promotions, but received positive feedback not only from O-Band fans but also from campaign participants.
With increasing requests for merchandise sales with each campaign, the company planned this collaboration with popular illustrator Tobimatsu Shoichiro.
The appeal of Tobimatsu Shoichiro's illustrations lies in their unique worldview, where warmth and cuteness created by hand-drawn techniques blend with a humorous atmosphere expressed through delicate lines.
He has expanded numerous stamp collections featuring his own illustrations, with such popularity that WEB sales events almost always sell out completely. While Tobimatsu Shoichiro creates many animal illustrations, "bear" illustrations have particularly passionate fans, and in the past, a "Bear Stamp Pre-Order Event" was held.
This stamp set is a unique creation where Tobimatsu Shoichiro's worldview meets O-Band's iconic brown and yellow box and "Waguma."
Stamp Lineup
Not only featuring Tobimatsu Shoichiro's appealing illustrations, but also highly versatile and easy to use. Rubber bands are scattered throughout with spaces for dates, days of the week, illustrations, and more—simply stamp and write for easy customization. The lineup is perfect for planners and message cards, as well as decorating everyday items.
You can also enjoy displaying them when not in use. The box, recreated in soft-colored paper at the same size as the O-Band 30g package, looks like playful stationery when placed side by side.
