Thank you for the info!MrsPancakes said:You should only ship very small snails in a bag of water. For larger snails, use a 12oz container with a lid. Put a damp paper towel in the bottom and wrap the snail in another damp paper towel. Place the container of snails in a box with loose fiber insulation packed tightly. They will have enough air for up to a week. Depending on the weather expected during transport, you may need to add a heat/cool pack to the top of the package with the insulation between the snail container and the pack. Hope that helps.
