We got the water bottles at CTI in 2011... Don't know why you would want them. The top and base are both metal. Metal. Sun. High temps. Sand. Huh??? Yeah, the metal gets scorching hot, as does your water. We tossed them. Happy to have the plastic bottles of Wata at CSA!
We were given 2 water bottles wrapped up with a ribbon on arrival in CN because we are repeaters. We loved these bottles and filled them with ice from the coke machines and added water then went for a long watch along the beach. The only thing about them is the logo came off before the end of our 2 week trip.
