heres my thoughts... take mason jars.. place them into boiling water, heat the glass up up, take 1 jar at a time out of the water, dry out the inside, moving swiftly, place the dry cannabis into jar until full, place lid on and seal up, place sealed jar into dishwasher.. Fill a bunch of jars this way to make them air tight, then give them a spin through the dishwasher to remove any resin glands or anything that could have contaminated the outside.. Then, go and buy the packaging you want it to go into, and keep the box away from any odorous drugs.. pack up up tight with lots of packing popcorn. tape it up, keep it clean looking on the outside and go for overnight. UPS Please someone go through this. i have not done this but i am lookin at starting up a business in this field
