If you plan on storing these prints for a good while its best to not keep them in a tube. I usually just keep them flat under my bed sandwiched between two acid free white boards from the local craft store. Also I will be ordering some of these since I will be having quite a few prints coming in this year https://www.framedestination.com/bags/protective_crystal_clear_bags/item/BGPRBA/ just gives them extra protection.
