Fun Standard Launches 'Shorui Mamoru-kun Black Type', an Opaque Thick Document Holder under 'BELLEMOND' Brand

Fun Standard Co., Ltd. (part of the RKB Mainichi Holdings group, headquartered in Onojo, Fukuoka; CEOs: Ryosuke Oya and Hiroki Sasamori), under its brand 'BELLEMOND,' has launched the 'Black Type (5-pack)' as the newest addition to its bend-resistant 'Shorui Mamoru-kun' document holder line as of May 2026. Designed for information and privacy protection, this opaque folder keeps contents hidden.

Key features include: 1. Opaque black design for privacy protection: Made with opaque matte black material on both sides, ensuring documents like contracts, estimates, and customer data remain confidential. The matte texture is designed to be elegant and resistant to fingerprints and scratches.

2. 0.5mm thickness for durability: Approximately 2.5 times thicker than standard clear files, this rigid 0.5mm design prevents bending and wrinkling. Its stiffness allows it to serve as a writing pad when standing.

3. Comfortable design for easy document access: Rounded corners prevent damage to bags or hands, while a large notch on the side allows for smooth document insertion and removal.
