I need to ship 4 mystery snail egg sacks and would like some advice on shipping them. I was thinking that I could wrap each egg sack in damp, just barely wet, paper towels, place in a plastic container. wrap in bubble wrap and place in a small priority mail box. I have various size plastic containers and was thinking that a vitamin bottle or small fast food side dish plastic cup for each egg sack would be alright. I have never shipped eggs before. Any advice would be greatly appreciated.
