Such types of Spatial tools were old and, thus, should have been cheaper. However, Ozul knew that it wasn't the case in this.
Since they did not require to build a connection using blood or Mana, people had to put their hands inside the Spatial pocket physically.
Creating those Spatial openings required more effort than stabilizing the space inside after hundreds of years of trial and error.
For such reasons, a Spatial pouch with the same amount of space inside it as the latest Spatial tools cost significantly more. Not to mention, she would have to find an antique one, which would probably be sold for many times more than its original price.
However, Hana did not let Ozul wait for much longer as she came in, bringing a small fist-sized pouch with a red string used to close it off from the top.
From the expressions on her face, anyone could tell that she was exhausted. She presented the pouch to Ozul before she sat down on the couch.
