These are truly beautiful water containers. The colours are stunning. They are water tight. They are also lighter in weight than I thought and being painted they won’t tarnish on the outside. I keep them on the kitchen surface and it has definitely made me drink more water as I try and finish two bottles a day. You can’t taste the copper influence and amazingly the water appears cool even though it sits around in a central heated house. I find drinking a lot of water from the tap can make me feel sick especially in the morning but I don’t get that with water from these bottles. I kept 3 and gave 3 away and my friends were delighted.
