Bag of the Lost & Found

Manipulated by magic, this bag was once a normal bag of holding and shows its original nature (and look) at the start of each day. However, it becomes warped with each use of its special features and looks more like a ragged leather satchel as it is used until the next sunrise.  Powerful magics were used to give the bag semi-sentience, which leads to behaviors not seen in other bags of this type. When asked for a thing that does not exist in the bag, it will seek out the nearest matching thing within range (500 feet) to fulfill the requestor's desire. The bag creates a small portal near the requested thing and a temporary demi-plane within itself, these pull the thing into the bag for storage and retrieval. Once the requested thing has been obtained, the bag will create a small portal within itself to allow the requestor to reach into the temporary demi-plane and retrieve the object; this whole process usually takes less than a second. The temporary plane only exists as long as the requestor's hand remains in the bag and disappears once the requested thing is removed from the bag. 

Due to its semi-sentience the bag often creates unstable portals, these portals have increasing chances of failure with each use (+10% failure rate each time, working flawlessly on its first use of the day). If the thing is removed from the bag's demi-plane, or more than one thing is pulled into it, the temporary space disappears and anything remaining inside will be deposited onto the Astral Plane in a random location. The bag is capable of finding specific items, and even beings, by name if the requestor is familiar with them and thinks of that thing clearly while reaching into the bag. Specifically requested things can be retrieved from infinite distances and across different planes of existence, though when retrieving things in this manner, there is only a 10% chance of success.

Like any bag of holding, the interior space considerably larger than its outside dimensions, roughly 2 feet in diameter at the mouth and 4 feet deep. The bag can hold up to 500 pounds, not exceeding a volume of 64 cubic feet. The bag weighs 15 pounds, regardless of its contents. Retrieving an item from the bag requires an action.

If the bag is overloaded, pierced, or torn, it ruptures and is destroyed, and its contents are scattered in the Astral Plane. If the bag is turned inside out, its contents spill forth, unharmed, but the bag must be put right before it can be used again. Breathing creatures inside the bag can survive up to a number of minutes equal to 10 divided by the number of creatures (minimum 1 minute), after which time they begin to suffocate.

Placing the Bag of the Lost & Found inside an extradimensional space created by a handy haversack, portable hole, or 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.

Renewed:
Each day, at sunrise, the bag reverts to its original "renewed" form and looks like a normal bag of holding, it will retain this look until it is used to draw an item into itself.

Unstable Portals:
While the bag is in its "renewed" state (aka its traditional Bag of Holding form) its first portal will work flawlessly. After that, there is a 10% chance (increasing by 10% with each use) that the unstable portal will collapse early inside the bag, pulling the user into the demi-plane with the item they requested (when an item is successfully retrieved); the bag will look more ragged with each attempted use of its ability. Once a portal has failed, the bag will be unable to open any new portals until the following day when it reverts to its "renewed" state.
