The bags are stamped in black ink by the tape you open it with. Not on the tape itself but on the bag by the tape.My 600 is marked 5D06 APR03141 0305 the AQ500 is marked similar except the date(I think) says APR02143. I think this is the date stamp Bill but it could be something else. I tried to get a picture but it's pretty overcast here today and the black ink doesn't show up on the blue bag. I'll get a picture later when I get to the farm and post it.


It's true hard work never killed anybody, but I figure, why take the chance?
