Positive: Envelope, packaging and extra stealth shipping was excellent. No problems with customs. Great! Negative: Chems were placed in hurry into zip lock bags and there were a lot of residue outside the baggies. My 2 g chem was divided into 4 little baggies instead of one. Also as a tip: please develop more discreet ways of packaging the products. Be creative. I would pay a lot extra for to be able to relax and not worry about customs. Also tell very specifically how you prepare these envelopes and how can make us sure it comes safely to my door. All and all great service. Will return definitely!
