Tall glass candle holders (Sonning RG4)

These are about 30cm tall. They were a present many years ago and I think might have come from Yankee candle - the candles that fit are cylindrical, approx 5 cm tall, 3.5 cm base (a little wider at the top). Will need some cleaning up as there is some candle wax residue on them. Hopefully someone will make good use of them - they are pretty!
