Two classic Dansk Designs Ltd candle holders, designed by Jens Quistgaard, Denmark...
Dark green moulded glass, with the logos to the bases. Designed to hold and support a pillar candle and catch the drips, but also suitable for balancing a wider tapered dinner candle, or tealight. These were mass-produced Scandinavian pressed glass candle holders from the late 1960s or 1970s. They look great stacked up and in a cluster - my parents had a bunch of these in about 1967.
In very good displayable and usable condition. Being pressed glass they all have moulding lines and small bubbles from time of manufacture. No chips. Stamped to the bases with 'IHQ' for Jens Quistgaard.
Each one is roughly 6.5cm tall x 7cm wide at the rim. Inner hole is about 3.5cm wide. Inner 'shelf' for a wider candle is 6.2cm wide. 
Perfect prop for a Mid Century interior, especially around Christmas!
Price includes P&P to the UK. Price is for the pair.
