Each earring listed is one of a kind.  They are made at random and never purposely or exactly duplicated.  All origami tsuru (crane) and stars are clear-coated with a protective sealant to protect the origami paper and keep the finished product stiff.  The sealant DOES NOT make the item water proof so please be careful when handling or wearing them.  The origami tsuru are made using 1" x 1" squares that are cut from the larger sized paper, so print designs will vary on each finished product.
