On 5th October, I bought one of your expensive "Apollo" fountain pens from Julian’s(朱利安公司), a big department store of this town. Unfortunately, I have been unable to use the pen because it leaks(漏墨水). I am very disappointed with my purchase. On the advice of Julian’s manager I am returning the pen to you. Please arrange for the pen to be fixed or replace it with a new one and send it to me as soon as possible.
