These are NOT from the Kai Professional line! The 5000 series are Kai’s consumer-grade scissors. They are excellent scissors (we have a bunch of 5000’s in addition to the 7000’s), but the two lines should not be confused. The professional line is quite a bit more expensive.
[edit] Massdrop changed the title of the drop, eliminating the “professional”. Thank you! As I said above - still excellent!
