Sparking the imagination, Fairy Doors are a well known addition to...well...anywhere really. They go inside against walls or under the staircase, outside in the fairy garden, against a tree.
(As this is made from wood, if you have it outside in an unprotected area it will deteriorate with the weather over time.)
Size is 14.5cm wide by 15cm high. Sold in packs of 3's.
