These heavy gauge, hand hammered flasks are made by an international cooperative of master copper artisans with workshops in Austin and Santa Clara del Cobre, Mexico. The flasks are TIG welded for a completely seamless construction and are tin lined for stable liquor storage. The precision machined stainless steel cap provides a note of contrast. Copper funnel included. Available as Boot Flask (Tall 5 oz.) or Hip Flask (Wide 7 oz.).
