In this price range there are a lot better brushes...
First of all they come without a tube... Usually the tube protects my brushes when in my stick bag.
The plastic grip feels really cheap, and it is really sticky and really not very comfortable to play with.
The wires do not produce the sound I thought they would when sweeping. I really like the vintage sound that regal tip brushes have, and I'm always after that... These brushes sound, look and feels cheap.
I would never buy them again...
