described by the seller as a 'wine cooler' - although I'm not sure what it means in this case as too small a diameter to accommodate a bottle. Sizes are, about.........4.5" tall with a rim diameter of a tad over 4" which narrows a little toward the base - slice cutting to the lower half and large quality ground/polished pontil depression and outer foot rim with fair amount of wear.
A lead glass ring which goes on for ages, and with the looks of some considerable age.
The seller might have meant to say 'wine glass cooler' - but in the absence of opposing lips it would seem unlikely (and probably too narrow anyway) - neither is it like any of the finger bowls I have, or seen.
But it may well turn out to be one of these items, in an unusual guise. So opinions sought please, and thanks for looking
