Beautiful cup with an unsightly problem

I think the cup outwardly beautiful, she looks classy and is with her red floral design held a real looker. The cover, which you can hang up is kept in white and closes the cup from the brew. There is also an integrated tea strainer, which can be attached with a small hook on the cup and relatively tight manner, so that hardly comes loose tea into the drink. Visually this cup's really a joy to behold.

The size is also great. The cup is very high and holds nearly 500ml, which is much more than the rest of my cups. Unfortunately, no Henkel is present, because the double-walled cup is supposed to be good tempered. Sorry but that is not functioning properly, after some time, you can easily touch the cup of course but just with very hot water and the cup wall is very hot! That's a pity and makes the cup a little impractical because no one likes to drink lukewarm tea. That it can work but, I have seen in other double-walled cups. If you can overlook that, you have a beautiful mug that also great for a present.
