Frequently Asked Questions (FAQs)

1. What is the point of drinking a flask?

What Is A Flask Used For? The quick answer to this is for an individual to simply carry a preferred liquor to an out of the home gathering or event where drinking is appropriate.

2. What material is best for a flask?

Some have a detachable bottom part that serves as a drinking cup – very handy in situations where drinking straight from the flask is not advisable. But stainless steel, with a good combination of hygiene, price, and resistance to deformation, is the material of choice for hip flasks.
