Scroll Case (or Map)

A bone, leather, or wooden scroll case easily holds four scrolls; you can cram more inside but retrieving any of them becomes a full-round action rather than a move action.

Source Advanced Player’s Guide

You must destroy the scroll case to damage its contents (hardness 2 for leather or 5 for wood, 2 hit points, Break DC 15). A scroll case is not water-tight.
