More Than a Spare Ball
The Hammer Black Widow Spare+ combines a polyester cover with core dynamics that help bowlers shoot spares accurately and handle very dry lanes or short patterns with low oil volume. Its White Diamond finish adds pearl sparkle to the familiar Black Widow look.
Gas Mask Core
The Gas Mask core provides an additional reaction option when lane conditions become extremely dry. Core designs vary by weight; see the core images and specifications below.
