WAS £17.50, NOW £12. Our silver-coloured 7 strand Accuflex thread is a steel-coated nylon thread which is incredibly strong. Another name for this thread is 'Tiger Tail' because you can't break a tiger's tail (can you catch a tiger?). Basicly this thread is unbreakable unless you use a pair of scissors. The price is for a 50m reel, which is a 30% discount on the per metre price.
