Bag of Preservation

Originally created by alchemists and brewers as a means to store their more volatile or rot-prone goods for long distance travel, Bags of Preservation keep whatever object is stored inside them at freezing or near frozen temperatures. It has seen much use across Faerun over the centuries and is now regarded as a mildly common or uncommon magical item. Item's prone to rot, distillation, degradation, or breakdown in normal conditions are rendered stable while inside the bag.
