200-220 mm long and 23 mm diameter. For example Skånska Stearinljusfabrikens or Liljeholmens kronljus. You can also use rustic candles from ICA or IKEA.
The sturdy glass can be washed in a normal dishwasher, restaurant dishwasher or by hand.
Heat water in for example a kettle. Hold the foot with a cloth, since it gets warm when you pour hot water on it. Pour the water on the foot - the stearin will melt an can be poured off. Wipe with a wash cloth. Done! The candle holder is as good as new. Please note: The candle holder feet are sturdy but should not be washed in a dishwasher, just the glass.
