These dummy trunks are made from Old Temple Pillars. This one species of material does not require drying - the wood comes from old castle/temple pillars and ancient constructions, not new trees. The wood is 50-300 years old in every case. These are best suited for arid environments. We believe this wood is Ulmus parvifolia, commonly known as the Chinese or Lacebark Elm. It has been described as "one of the most splendid elms". The wood can withstand cold temperatures very well. This wood has always made a great dummy!
