Seen it here a couple times. I also researched of how long it takes till dry ice dissapears etc. But will wanyone be able to feel or see that theres dry ice in the package? Do you guys just put it in  a cardboard box? Since that will probably leave traces of humid inside.
or maybe wrap the inside with plaxtoc so there wont be any humid stains but wont that look suspiscious?

anyways what im getting to is how can i do this method with the least traces as possible?

Dry ice method is mostly unnecessary. Tell me what u want to do with it?
