Where is the expiration date stamped on your Jin.?

I just got 5-more kits from my guy and everything checks out(The # Tag and security fibers all jibed) the only thing that strikes me as off is the expiration isnt stamped in the spot on the back provided for it but in the front right side anybody else?

On the side of the box ((not where is supposed to be (expiration date:....Batch Nº:...) but in the other side, the side used to open the box)) and on each vial.
