Dear Sir or Madam,
I regret that I did not make myself clear enough and may I hereby again explain our situation.
As the papers for making top surface of your boxes are no longer available for sale anywhere, the factory had ordered other papers of similar colour to replace the previous one it used but unfortunately the
colour still could not be exactly the same as the previous one after many
trials.
However, the factory hopes your firm shall agree to use a similar paper as a subsitute , the sample of which has been sent to you earlier. If your reply is positive, the factory warrants to, free of charge, make 200 extra boxes as replacement for your present stock of boxes, and itself stock up more of those papers to make sure all the boxes made in the future will be of the same colour.
I shall be grateful if you will accept the offer and your
early reply will be much appreciated.
Yours faithfully,
XXX
