Flip the cap to reveal a smaller area of suction which can be used on places like fingers and toes.
The suction can help bring splinters to the surface of the skin for easy removal (very convenient for children who may be afraid of using tweezers).
The handles are specially designed to scrape out a bee stinger left in the skin. Never try to pull the stinger out, you may push more venom in the skin. Simply flick the stinger off with the scraper and immediately use the suction.
Wash the removable end cap with soapy water or an alcohol wipe between uses. Avoid getting the pump portion wet to prevent the tool from losing its suction ability.
