Flask Discription(from the Manufacturer):

• QUALITY: Not all flasks are created equal! Can you find a cheaper priced similar looking 6oz flask? Sure, but there is a reason... You get what you pay for. Even the other sellers selling "Premium" flasks don't compare to ours. Our premium heavy duty 6oz flask is made with .6mm thick #304 food grade stainless steel with laser welded joints.

• MATERIAL: Our premium flasks are only manufactured with #304 (18/8) food grade stainless steel. Cheaper flasks are made with #201 (18/10) which ARE NOT food grade material. Using lesser quality steels in the containment and/or production of food and beverage products can lead to the leaching/corrosion of the inferior metal and potential ingestion of toxic metals.

• THICKNESS: Our 6oz flasks are heavy duty and 50% thicker than other flasks seen on Amazon. They are made with .6mm thick 18/8 food grade stainless steel. Nearly all of the flasks you see are made with .4mm-.5mm compared to our .6mm. When you pick up one of our flasks you can tell right way it's made to last!

• LASER WELDED: This 6oz flask features laser welded joints compared to hand welded. This means the flask will have smooth edges without any holes or rough edges and won't leak. All of our flasks are leak tested!

• VOLUME: Not to big, not to small! This flask holds 4 shots (6oz) of your favorite liquor.
