If vendors were a little more creative/ flexible with shipping you wouldn't have to worry about love letters : DarknetMarketsNoobs | Torhoo darknet markets
Crush pills and hide them in a drink shake package/ secret compartments in objects. Putting drugs that are usually solid and liquid form and putting them in container...There's tons of more creative methods to do but instead they just wrap your drugs in plastic or foil and call it a day. I would pay extra for ACTUALLY custom stealthy shipping. A buyer is putting the threat of jail on the line. Might as well spend the extra.
