Okada Shokai Co., Ltd. (headquartered in Osaka City, Osaka Prefecture; store manager: Kojiro Okayama), which operates the online seal shop 'Hankos,' has started selling the 'Haikyu!! School Stamp Collection' through its official online store. This special seal set is designed for fans of the anime 'Haikyu!!' and includes a custom seal case engraved with the school name and icon of one of the featured schools, paired with a personalized seal engraved with the customer's name.

The 'Haikyu!! School Stamp Collection' is inspired by standard school-issued seals, offering fans an immersive experience into the world of 'Haikyu!!.' Each set comes with a specially designed 'dedicated seal case' featuring the cool, stylized school name and school icon. Even when carrying it around, fans can feel close to their favorite school.

There are six schools to choose from: Karasuno High School, Aobajosai High School, Nekoma High School, Shiratorizawa Academy, Wakatoshi Academy, and Inarizaki High School. Supporters can select the school they cheer for.

Two seal design options are available. The 'Standard Design' features a simple engraving of your surname or full name, while the 'Volleyball Design' creatively incorporates the name within a volleyball motif, adding a playful touch.

The seal materials come in two types: 'Tsuge' (boxwood), known for its warm, natural feel that becomes more comfortable with use, and 'Kurosuigyū' (black buffalo horn), prized for its sleek black finish and excellent durability. Both are authentic seals designed to be used with red ink paste, combining practicality for everyday use with collectible appeal.

The seal measures 12mm in diameter, making it ideal for personal seals and bank seals. It can be used for receiving deliveries, signing documents, stamping on children's communication notebooks or school forms, and is eligible for registration as a bank seal at most financial institutions nationwide (the Standard Design can also be registered as a jitsuin, or official personal seal). With just a 'pom!' stamp, fans can subtly express their passion for their school or club in everyday situations.

The 'Haikyu!! School Stamp Collection,' with its meticulously designed case, is a must-have for any 'Haikyu!!' fan.

While seals are often seen as formal and serious, we will continue to create unique and fun product concepts that resonate with enthusiasts, aiming to increase interest in seals among a wider audience.
