The flask as we know it today dates back into the 18 century. Throughout the years, people have filled these flasks with their favorite liquors. Case Maestri took the idea to create a full ready-to-serve, hip flask of tequila for all the flask aficionados. What is better than buying a typical empty flask in the store? Buy a ready to serve flask with great quality tequila to enjoy by yourself or to share with others. The best part is it can be refilled and reused after you finish the delicious tequila inside!
