defective products 42

I finished 4 packages and now I can say that there are two layers in each packet that have a quality problem: it lacks the band with vertical dashed green lines and therefore where we must stick the flaps is very smooth, result: the tape will not stick at all and therefore can not close the layer. Usually I buy that brand of product layers on organic sites, this time I bought from amazon because the price quoted was cheaper. But with 8 layers defective thrown straight in the bin, I think finally it came back to me more expensive ...
