Vater Practice Tips are made of a durable and pliable rubber material, so that they can easily be put over the tips of any drumsticks. They provide a quick and easy way for drummers to quietly practice anywhere they may be without having to carry a heavy practice pad with them. They can also be used while playing acoustic drums for a unique tonal option with reduced volume as well as on electronic drumsets for less attack on the pads. 2 pairs included.
