Uses the Sméll Ball to scan smells and collects the data via Bluetooth and there is an encyclopedia page on that specific smell. It can also scan by itself, but using Bluetooth would be more high quality.
Links with the Sméll Dex, and pressing the button on the front of the ball can scan the smell in the air. It can also be opened to keep air for further purposes as well.
Both of them together costs 3999 RMB.
