I wouldn't recommend paper towel just incase it deteriorates& the snake happens to pick some of it up in its mouth it's very expensive so have paper towel removed from your pet id personally recommend the sponge in a zip bag however I have no experience shipping I just know snakes & paper towel don't go well together in any situation worst case see what happens & if you have to have reciever bathe the snake in Luke warm water if it has any stuck shed & give it a day if it's still stuck give her another bath & help her remove it yourself (keep in mind snakes like doing it alone so give them a chance to do it themselves)
