Hunter Specialties' Solid Scent Wafers have a pure concentrated scent that masks odors. Developed by a leading wildlife biologist, the scent can't spill, freeze or wash away. The wafers can be pinned to clothing or hung from hunting site for hours of scent coverage. To revitalize the wafer, return it to the resealable container and it will return to full strength for your next hunt. There are three wafers per resealable container.
