The Cardboard Storage File is designed to facilitate the storage of blocks and slides. This economical system is less expensive than metal filing systems but still offers the convenience of drawers for easy retrieval of file contents. Strong and lightweight due to the unique corrugated construction, the system comprises of five file boxes for either blocks or slides or a mixture of both. These are supported by an outer shell, which stabilizes and enables the units to be stacked together.

The single units are 10 cm x 29 cm. The block file can hold 500 blocked out cassettes (2500 per system) while the slide file can hold 2000 slides (10000 per system). Both offer the convenience of easy retrieval from partitioned drawers.
