A New Standard in Delivery Convenience: The GXB28

On April 15, 2026, Tajima Metal Work Co., Ltd., a subsidiary of Sanwa Holdings Corporation, will roll out its highly anticipated GXB28, a battery-operated delivery box designed for modern residential needs. As urban living evolves, the demand for innovative solutions that simplify package delivery grows, and the GXB28 aims to meet this challenge head-on.

Key Features of the GXB28

The GXB28 distinguishes itself through a variety of innovative features that enhance usability and convenience:

1. Battery-Powered and Maintenance-Free: This new model employs a lithium battery for its locking mechanism, eliminating the need for electrical installations, thereby allowing usage even in locations without nearby power outlets. Its long-lasting battery is expected to provide approximately ten years of life, although actual duration may vary based on environmental conditions.

2. User-Friendly Operation: The GXB28 has been designed to facilitate seamless transactions between residents and delivery personnel. When delivery personnel secure the box, it automatically locks the resident's side, negating the need for them to unlock the delivery side manually.

3. Enhanced Security Features: To prevent unauthorized use, the GXB28 requires unit numbers before entering pin codes for unlocking. In case of forgotten codes, a remote emergency unlock feature via management companies is available, enhancing overall security and reducing management burdens.

4. Compatibility with Existing Mailboxes: The GXB28 integratively fits with the currently marketed Sanposta MX-92-28FB mailbox, allowing homeowners to use existing setups without extra wiring, thus simplifying installation in both new constructions and renovations.
