DR-7 Solid
Our DR (Delayed Reaction) series of coverstocks are typically used in conjunction with a polished finish. The combination of the two produce great length with a strong reaction at the backend of the lane.
For the first time, we are offering this cover in a solid version with a sanded finish. By doing so, we created the strong midlane reaction expected from the sanded finish, while enhancing the reaction at the breakpoint do the inherent chemistry of the DR series.
