This is a Venetian glass swing glass/rocking glass I received as a gift. The point is that it's a glass that sways gently but doesn't tip over. The logo-like mark is the manufacturer's logo sticker. How about it as a gift for someone who likes to gamble or for good luck? I've never used it, but there are sticker residue marks on the bottom of the glass, so I'm listing it as "like new." I think the sticker residue can be removed by rubbing it.
