The cup is really shapely, big enough and keep previously sealed. The described by many other buyers sticker problem I could solve. The adhesive used is fat-soluble and becomes soft when heated. So I initially placed the cup in warm water to remove film and paper components of the label can. Then I rubbed the splice with olive oil, rinsed with hot water and washing up liquid, again oiled, then finally flushed. Now the label has really disappeared.
