Thanks, Michael, you can't argue with a label! Having looked at the piece, I maintain that it's a vase, not a candle holder as the eBay seller states. The internal diameter of the shaft is too narrow for a tealight and the depth would be useless for a candle unless you wanted to waste 9cm of the bottom.
I haven't looked at that website for quite a while, Ross, so have just spent the last hour looking through it - always good to revisit and re-acquaint myself with Finnish glass although in the case of this vase, looks to be the adjacent country.
