These felts are very low/thin, so don't buy these for any cymbal. These are good for special applications, such as putting a splash on top of a crash, or adding to a normal size felt to tighten down the cymbal more. They are conveniently priced and of good quality, but should be bought only for special applications.
These are great felts! I use these in conjunction with the Gibraltar 8mm Cymbal Sleeves and the Gibraltar Tall Cymbal Felts. For my ride and china, I use a tall felt underneath the cymbal and a tall felt on top. For crashes and splashes, I use a tall felt under the cymbal and a short felt on top. I find these combinations allow the right amount of movement and security for the types of cymbals.If you use only these short felts, you need 3 or 4 to ensure your cymbal doesn't wave around uncontrollably. If you use only the tall felts, you only need 2 to ensure your cymbal is stable.
