+ Good for the environment, less waste + The drink from it is pleasant + Porcelain º minimal silicone smell / taste at the first use (pre-cleaned with warm spüliwasser 15 minutes), but hopefully soon veschwindet º through the double wall of the cup is hard, but I like to take into account, to avoid having to drink from a plastic thermo mugs
if you want to keep the coffee warm for a long, you should buy a thermo mugs. This mug is for coffee to go: on the way to work and not drinking hours later at the office.
