This bag is what every inventor is dreaming about.

It has an interior space considerably larger than its outside dimensions, roughly 2 feet in diameter at the mouth and 4 feet deep same as a bag of holding but instead of storing everything you put inside it you store gold inside this bag and can pull out materials (at any point not necessary when you store the gold) that can be used for your inventions of value equals to double the gold you have stored inside.

Also tools used for tinkering can be stored to a small parchment of the bag. Only the one who is attuned of the bag can pull things out and in the bag. If anything else but gold or tinkering tools is put in the bag it gets spit out same if someone else but you person puts something in. The bags weight 15 pounds regardless on how much gold is inside and can hold up to 25000 worth of cold and up to 10 tools

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 materials of worth equal to the gold that was left inside spill forth as well as any tools stored inside it.
