Archival Base & Lid Storage Box 370 x 264 x 105mm

Description

A durable two-part storage box designed for long-term archival use. Each box consists of a separate base and lid, both double-walled on two sides. When closed, the box becomes triple-walled on all sides, providing excellent strength and rigidity — ideal for stacking and protecting contents during storage.

Constructed from 1.3mm solid archival box-board, this design offers both stability and protection while maintaining a smooth interior finish to prevent abrasion.

The boxes are supplied flat for efficient transport and storage, and can be easily assembled without glue or staples. Locking tabs slot neatly into place to hold the structure securely together, ensuring a clean and professional finish suitable for museum, archive, and library environments.
