Id like to "zip" both sides of a portable external hard drive case with a drive inside and its connector cord (external drive port to USB-C) protruding out.
Its to keep the drive safer or cushion the fall if it falls accidentally.
Since it's a one-way zipper you probably have to bring some of the cord around the inside to the end and zip to there. If you're worried it will unzip you can possibly use a safety pin 🧷 across the zipper behind the pull.
