Here’s how I’m packing cuttings, rooted clones just skip wet paper towel, just make sure the rock wool/rooter is moist.
Make sure the cutting fits lengthwise into the bag
Damp but not dripping paper towel around the cut stem
Plastic wrap
Roll so the zipper of bag acts like a spine, leave a bit of air in the bag. I use tape to keep the bag rolled up.
Place them into another bag, add some padding material into the box
