Title says it all. Also what would be the most cost effective?
International? Or Domestic?
I usually package base in a little 200ct box or something, and tape the crap out of it and put the label right on the box. I will usually line the inside of the box with thin decoys to protect the base a bit. First class will work if it's under 13oz domestically, or under a few pounds internationally. Otherwise, domestically, Parcel Post would be the next most cost effective.
If you want to be extra careful, place the 200ct box in a larger box with packing peanuts.
