KS16 Telescope Type Storage Box With with tube insert
Roll storage boxes suitable for large-size and delicate archival objects. (e.g. geographical/architecteral maps, textiles etc.) The tube in the box is made from spirally wound conservation board and is supported by two layers of corrugated board. In this way absolutely no pressure is exposed on the stored object. Two textile ribbons enhance easy manoeuvrability of the tube. Delivery assembled and upright.
