【正确答案】Dear Sir,
   Subject: About the Packing
   On 10 July, we received your consignment of 40 cardboard cartons of steel screws.
   We regret to inform you that 10 cartons were delivered damaged and the contents had spilled, leading to some losses.
   We accept that the damage was not your fault but feel that we must modify our packing requirement to avoid future losses.
   We require that future packing be in wooden boxes of 20 kilogram net, each wooden box containing 40 cardboard packs of 500 grams net.
   Please let us know whether these specifications can be met by you and whether they will lead to an increase in your prices.
   We look forward to your early confirmation.
   Sincerely yours,
