Seiban Held a graduation ceremony for school backpacks alongside a new product launch event.

At the outset, President Takaaki Izumi addressed the current situation where schoolbag sales are declining due to the declining birthrate and the industry trend of earlier sales peaks. He stated, "We aim to increase sales even as the number of children decreases by enhancing quality and design to sell high-value-added products. We want to steadily implement our slogan, 'Durable and Sturdy, 6 Years of Peace of Mind!', and meet our customers' needs."

Following this, children who had used "Tenshi no Hane" backpacks for six years were invited to participate in a backpack graduation ceremony.

President Izumi commented, "While school backpacks are typically associated with new first-graders, we meticulously handcraft ours to last six years. Because we are confident in our quality, we want to hold a graduation ceremony for the children who cherished and used them for six years, and for the backpacks that witnessed their growth."

At the graduation ceremony, DAIGO, the "Angel's Wing" commercial character, served as the presiding officer. He received the backpacks used for six years from ten children graduating elementary school this spring and presented them with graduation certificates and commemorative trophies. When interviewed by DAIGO, the children reflected on their enjoyable school life, saying things like, "I remember the first time I put on my backpack and went to school excitedly."
