Clamshells & Phase Boxes





Etherington Conservation Services designs and constructs various enclosures for the protection of library collections and archival materials. Clamshell boxes, phase boxes and other enclosures create a microenvironment for the book or object inside. The book is protected from light damage, abrasion, the effects of pollution. In addition, the microclimate acts as a buffer to fluctuations in temperature and humidity.
Boxes are titled either directly on the covering material or on attached labels. Labels can be laser-printed or stamped on paper or leather.

Phase Boxes
The Standard Phase Box protects brittle or deteriorated volumes effectively and economically.  Custom-made from high-quality, acid-free grey/white board up to 12" x 12" x 2" with title stamped in white foil.
