Delivery 4 days. Mug bomb! The strainer came to my other thermo mug. Hot water holds three or four hours, well, in principle, like all similar thermo mugs. I'm happy with the purchase.
So happy with this tumbler. It is so well made and with very good taste. Everywhere I take it, everybody asks me about it. It arrived a little slow (but it is not a problem of the seller) and very well packaged.
