Anti-fog liquid for underwater use, 20ml capacity, easy to use. *Since it is written in Korean, I am not sure what it is used for, but I believe it is an anti-fog liquid for glasses or goggles. I would appreciate it if someone knowledgeable in Korean could help. It is new and unused, but there may be minor scratches or dirt that are not easily noticeable. Please only purchase if you understand that it has been stored at home by an amateur. - Product Name: FOGSTAR - Contents: 20ml - Use: Underwater anti-fog liquid Fogstar, Korea, Made in Korea, Korean, Korean Cosmetics, Glasses, Goggles, Glasses Anti-fog, Goggles Anti-fog, Anti-fog, Mist, Disinfection, Spray, Disinfectant Spray, Anti-fog Spray, Rare, Scarce, For Underwater Use, Pool, Sea, Summer, Travel, Sightseeing
