This dark-brown leather satchel bag can hold up to six books, 30 pages of paper or parchment, and any writing utensils (pen, quill, ink, sand, etc.) - nothing else may be placed in the bag. This specific bag of book holding sports a symbol of Selune on the front. Moreover, though it may seem to weigh a lot depending on the size and number of books, it actually ultimately weighs 5 lbs regardless. The bag also has a sewn in component pouch that has dividers to separate materials used for different spell levels and several clear transparent packaging to pack materials for the same spell together. In addition, it has holsters for potions to hang off (Max 5.).
If the bag is turned inside out, its contents spill forth, undamaged, but the bag must be put right before it can be used again. Placing a bag of holding inside an extradimensional space created by a similar item instantly destroys both items and opens a gate to the Astral Plane. The gate originates where the one item was placed inside the other. Any creature within 10 feet of the gate is sucked through it to a random location on the Astral Plane. The gate then closes. The gate is one-way only and can't be reopened.
