Noted that the emboss code is A15A GF. Can you please confirm about the inkjet date on top lid again? Is it 2016/10/24(YYYY/MM/DD)? If so, the production date is 24 Oct 2013. There must be something wrong. Kindly check and confirm soonest.
From your comments that they are small wood pieces, we don’t have any wooden things in our production line. It would be great if you can send us the foreign material to check further on our side.
