KASEBoxes are archival boxes used to effectively and economically protect brittle or deteriorated volumes. They are custom made out of archival corrugated board, available in eflute and bflute. The base product is shipped blank and flat. Folding and titling is available for an additional fee. Standard titling is printed in ink directly onto the board. KASEBoxes are available in two standard styles: the KASEBox clamshell and the KASEBox portfolio. Unless otherwise requested when KASEBoxes are ordered, any items ordered as KASEBox clamshells but under the minimum thickness are automatically put into the KASEBox portfolio design. KASEBoxes are also available in the following specialty styles: the KASEBox telescoping lid box, the KASEBox slipcase (available only in bflute) and the KASEBox phase box. The minimum thickness for KASEBox clamshells and KASEBox telescoping lid boxes is 3/4″ in eflute and 1 1/4″ in bflute. The minimum thickness for KASEBox slipcases in bflute is 3/4″. The KASEBox portfolio and KASEBox phase box designs have no minimum thickness.
