I purchased this old badger brush a few days ago at an antique mall. I believe that it is made of celluloid and it came with a matching celluloid mug. At the store it looked kind of smashed and discolored, so I bought it with the thought of replacing the knot with a new silver tip. Well I decided to wash it in some brush cleaner re-vitalizer and it actually came back to life. It's shape became full again and the color got much brighter, when I used it, it was the softest brush that I have ever used. Is it rare for a 60 or 70 year old brush to be in such great condition? Oh by the way, I've used it 3 times and it's never even shed one hair!
