JC I do not know if you want to use my process but I put mine in styrofoam lids. I put the stones around and on top so they look like they are planted in the garden. But all I have to do is pick up the lids and move them.
I will take a pic tomorrow if it stops raining long enough to show you how it looks.
I order from Omaha Steaks and get at least 3 boxes a year. Also, when I get fish for my pond in the summer they give me a couple to transport my fish home. The lids are about 3" deep and I punch holes in for drainage.
