The space button is divided into ten levels based on size, with the lowest being G-type and the highest being SSS-type. Each level has further subdivisions. Pang Zhi's space button is a C-300 type, with a space of 300 cubic meters, roughly equivalent to a 100 square meter room. It's not too small or too large to hold things.
Of course, considering its level, it's already quite remarkable. Such space buttons are not cheap, and even with money, they might not be available. So, if auctioned in the black market, the final price would surely be higher than its market price.
However, Guan Jin eventually returned it to Pang Zhi. Although he looked down on a spoiled young master like Pang Zhi, Pang Zhi is still an underaged boy, and Guan Jin himself is wealthy enough not to covet a C-type space button. In fact, Guan Jin himself carries an A-type space button.
