Dear Ad Segers,
After reading your e-mail I am so unhappy and a bit boring because your so strict on the goods.
You should understand that most dog chews made by hand so we can not control every bone.
There are some a bit over or less average weight It is a nature of dog chews.
If you can not accept It is difficult to continue working for you.
Please confirm if you still need the last 3 container according to our quality?
Best regards./Pongsiri.
