Double Walled Copper and Steel Glass set is a unique handcrafted Art-ware. Outer Tumbler is of High Grade Stainless Steel to give it hardness against dents and inside layer of 99.99% pure copper give it all essential qualities of Copper. The laser printed flower retains its shine much longer then other artwork. Copper water should always be taken from the tumbler in which you can see inside otherwise it can be harmful as closed vessels can lead to formation of copper oxide. The purity of Copper is very important to extract its benefits. The shine of Copper can be retained by cleaning the tumbler with lemon peel and pinch of salt (of used lemons in house) once in a month. The Double wall will help the water to remain hot or cold for a longer time. Storing water in copper can leech some amount of copper to inside water and it reaches around 180ppb in 16 hours. This can go up to 450ppb in 7 days. WHO limit of 2mg/L (2000ppb). So from a dietary point of view drinking 1-2 liters of this water will give you 0.18-0.36mg (~25-35% of total daily requirement)
