First load, then shoot – it's that simple. The XL single-shot lubricant launcher is designed for one-handed use. Thanks to the convenient finger loops, you can fill the launcher with your chosen liquid and propel it into the body using simple thrust power. The single-shot launcher is equipped with a cover that prevents leakage before it's ready for use. The new XL size holds twice as much lubricant as the original launchers, allowing you to get to work faster.
