Don't waste your money! This company is a rip off. Claim to be environmentally conscious company but have them made in China. My coffee cup arrived damaged and they wouldn't send me a new one because it's not environmentally friendly. Really?! I was offered a measly £3 refund off a £30 cup. When I queried this I was brushed off. So it's fine to ship as long as you pay a fortune but not if they messed up. Also totally fine to have them manufactured in a country which is consciously polluting the environment and has no worker's rights. If I wasn't environmentally conscious myself I would throw it away on principle. I will stick with the £10 coffee cup I bought 15 years ago which actually keeps my drink warm.
