Product Review

Each flask is made of a durable BPA free food grade material. They are puncture resistant, leak proof, stand on their own when filled, and can even be frozen. (hot or warm water is not recommended). They are also great for sporting events, movie theaters, camping, fishing, golfing, or anywhere you'd like to enjoy a drink.

These are ideal for any non-carbonated beverage. They are odor proof, taste proof, and clean easily with soap and water.
