Cornwall Flag Coasters Cornwall Flag Coasters Cornwall Flag Coasters The St Piran flag of Cornwall £15.00 Sorry, sold. Please contact me if you would like me to make one for you. My coasters are formed by fusing a single clear, opaque or coloured layer with a second more decorative layer. These two are to celebrate that wonderful county, Cornwall. The black and white St Piran's flag.....a reminder of lovely holidays or reminder of home? They measure 10cm x 10cm (3.93 inches). Each one has 4 bumper feet to prevent the coaster sliding when used. UK free post and (careful!) packing.
