Personal note:
For this type of metal cups, it is probably quite difficult to implement a handle that looks as good as possible aesthetically, the cup is not bad, but it is not what I wanted either. I'm not returning it because it doesn't bother me that much, probably that's what the seller is relying on, although I don't think we're too many fans of this kind of product. I say let's be thankful that this niche still exists, as it is. I can't figure out if it's the real volume/quantity (250 ml), I'm probably used to bigger cups, that is, it seems small unfortunately, more for coffee than tea, you have to refill quite a few times at such a volume. There is also a kind of stripe on the mug, as if that's the design, it doesn't seem like a mistake, it's imperceptible, probably there is the solder, I don't understand, that is, the mug has double walls, which is an advantage over other models of metal cups that are just a soft sheet.
