Dear Mr. Carlson,

Thank you for your e-mail concerning the faults in the USB flash disks supplied to your order number 4698.

We have tested a number of disks from the production batch you mentioned, and agree that they are not perfect. We accept responsibilities for this and apologize for it.

Please arrange to return to us your unsold balance of 560 disks. We will be happy to pay the delivery fee. We have already arranged for 600 disks to be sent to replace the unsold balance. The extra 40 disks are sent with our compliments. You will be able to provide free replacements of any further disks about which you may receive complaints.

Once again, please accept our apologies for any inconvenience.

Sincerely,

Lucas Brown
