Thrilled (although not entirely surprised) by the success of our original 'Spare Pair' (three pairs are proven to be better than one now), we have created a new set with the more book-conscious in mind. Still with three pairs of the same dioptre on one card but this time with three different cool frame shapes to change up your 'look' too. Keep a different pair on the sofa, bed, 'library' or anywhere you fancy a chapter or two! Probably THE most useful gift anyone can give to anyone who loves books AND wears glasses.
