Just an fyi
Last year when my air force grandson was in South Korea I mailed him some chocolate chip cookies. The 1st time they arrived they were very hard. The second time I sent them I poked holes in a ziplock sandwich bag and inserted a piece of bread and placed it in the bag with the cookies. He said they arrived in great condition (other than he couldn't figure out why I sent him the bread in with the cookies )lol. Live and learn!
