Seal your loaded revolver chambers to prevent "cross" firing. Seals are presized for the caliber revolver, and are easily placed in each chamber without the mess of greases or lubes. In addition to providing a sure seal, Wonder Seal also lubes and clenas your barrel when shooting. Conveniently packaged in lots of 100 in a resealable plastic jar. Available for .36 and .44-.45 caliber. State preference when ordering.
