ProMark's most durable Forward 747. FireGrain is a patented heat-tempering process that transforms ordinary hickory drumsticks into precision tools with unprecedented durability. While keeping their original weight and balance, ProMark FireGrain sticks allow drummers to hit harder and play longer, naturally. No excess vibration, no space age gimmicks, just natural hickory hardened by flame. For a limited time, packaging and stick artwork may vary.
