When I got my scoby, it was sealed in a ziplock bag with about 1/2 C of tea. This ziplock was neatly folded up and placed in another ziplock, which was neatly folded up and then wrapped in packing tape. This pack was then wrapped in tissue paper, then in bubble wrap, and then placed in a paper packed box and shipped. They packed my Kefir marbles the same way. The tape wrapped packs were a little hard to open, but no leaks at all.
