Fullips Enhancers are designed using self-suction, not a pump. Self-suction allows the user to control the level of enhancement to create a better lip line and overall lip fullness. Getting suction at first can be tricky. If you have trouble contact us, we can help! Size is also important, we can help with that too! Can take about a month of use for max effects. Videos and FAQs also available to help. Made in USA of hard food-grade plastic. Provides a simple, non-invasive, temporary solution for fuller lips without the pain and expense of lip injections. Small enough to tuck into a makeup bag for use before touching up lipstick every day or just on special occasions! Choose from 3 shapes/sizes: Large Round, Medium Oval, and Small Oval. Results vary 1-4 hours. U.S.Pat.No. US8858472. Additional Patents Pending. *CAUTION: Read all directions provided in box.
