Serio

Developed under the Japanese office supply maker Sekisei, Serio (セリオ) is built entirely around no-nonsense workplace organization. Rather than decorative desk accessories, the brand focuses on hard-wearing essentials, water-resistant polypropylene file boxes, dual-fold clipboards, and modular document holders designed to withstand daily handling in offices, classrooms, and busy workrooms. Serio emphasizes durability, light weight, and straightforward utility, providing the quiet, functional structure needed to keep high volumes of paper tidy.
