bakelite button造句

• The jerkins from the Second World War had bakelite buttons instead of the brass or brown leather of the originals, and were each unique in that they were finished around the bottom edges with offcuts in a bid to eliminate waste . ( It has been suggested that many of the World War II jerkins were made up from leather left over from the Irvin flying jackets also in production in the UK-however, the flying jackets were made of sheepskin so this may not be the case ).
