The Revalor Implant Gun is the exclusive applicator gun for Revalor Implants. Always use a sharp needle. As needles become dull, they may tear tissue and make proper implanting difficult. After implanting, wipe the needle with cotton or gauze moistened with alcohol or other suitable disinfectant. Do not dip needle in solution or needle may become plugged. Replace needle when dull. Revalor Implant Gun comes with 5 needles.
