bag of unholding

This bag works almost identically to it’s commonly mistook predecessor “Bag of holding”. Except when an item is placed inside and the bag is closed and opened back up the item previously placed will be gone. Now you might wonder if the item you just lost is gone forever, but you might be wrong because instead of placing it in a pocket dimension the item vanishes instead to somewhere in the universe, you may ask where but you will have to find that out yourself.
