Query: Porto Sippers

These sippers arrived intact, minus one cracked leg (which I didn't notice at first) that ruined the balance of a sipper. I thought that they were a steal, but the glass is ugly. It isn't clear, it's dirty. All of this would have been a compromise worth making, but all of these sippers are different. The lengths of the neck all vary, from really short to barely enough. Non of them were broken, just poorly made. I would suggest investing slightly more for an item that wont aggravate.
