Bag of Holding

A bag of holding has an interior space considerably larger than its outer dimensions, roughly two feet in diameter at the mouth and four feet deep. One bag can hold up to five hundred pounds, not exceeding a volume of sixty-four cubic feet. Each bag weighs fifteen pounds, regardless of the contents within it.

According to Allura Vysoren, who used to occupy her time by making bags of holding, when such a bag is destroyed (for example, by placing one bag into another), its contents are jettisoned into the Astral Sea.

Vox Machina's Bags
Vox Machina obtained its first bag of holding as loot from an ancient druid barrow around sixth level. The group later learned of a bag of holding's limitations when they tried to store a creature, Dork the Ox, inside their bag. Anything living that gets stored inside a bag of holding dies. They also learned from Lady Allura that, if a bag of holding is destroyed, its contents are jettisoned into the Astral Sea.

Later, Tiberius purchased a bag of holding. Vex'ahlia kept a special "bag of colding" from the Slayer's Take that preserves biological samples.
