Interesting mug) metal, looks massive, in fact the volume of 250-260 ml. From the bottom of the battery and a thin rubber band, I think not very sealed, so I do not advise you to put it in the water (sink). Delivery more than a month, the thing is busy, if there is anything to mix)

Excellent, quality

Everything is fine, the volume of the Cup corresponds to the description. the volume of the filled liquid ~ 330-350 ml. Is OK

Cool mug) I recommend)

Thank you! Very cool thing at work for ponts. Is: DDD
