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? Although I have never used it, it is listed as "Like New" because there are sticker residue marks on the bottom of the glass. I think the sticker residue can be removed by rubbing it.
