FeedJlaI'd like to know as well, you really have to be leery of all leather products that don't disclose or show the stamp. I recently ordered a $30 belt that was advertised as "100% full grain" yet when I received it the back said "Genuine Leather" which is inferior grade.
Full grain > top > genuine> bonded>synthetic. Excellent marketing names to fool the masses.
monkifiedSame goes for badger hair.
Special Graded>Silvertip>Super>Best>Pure.
They must laugh at all the newbies. "I got a pure badger hair brush! It's so awesome!"
