Well, that depends on two factors, what you put in your flask and the local laws. While carrying a flask is not illegal, having liquor in an open container is illegal in many jurisdictions. Check you local laws to make sure you are adhearing to them. Or break the law, just don't blame us when you do.

That depends on how you classify a drink. The flask holds 6 ounces. Many regard a drink as 1.5 ozs, so that would be 4 drinks, but Baron La Croix tends to have a heavy hand when he pours. Just drain your flask and consider it one drink, when the prudes inquire.

1. Drink your flask clean or at least try not to let alcohol sit in your flask more than two days. 2. Empty the flask, if it isn't already 3. Throw in a few drops of dish soap and warm water, filling about 2/3rds of the the way up. 4. Close cap tightly and shake vigorously. 5. Pour out soapy liquid and rinse throroughly with warm water. 6. Fill it back up with booze and get to drinking. That's what you bought it for.

Your flask is stainless steal. But what are you made of? Probably a shit load of badass. cuase you are picking us such a dope flask.
