The Trekpak Case Divider System is a beautiful piece of design. It’s simple, it’s clean, and most importantly, you can switch up your configuration to your needs. It’s meant to replace the current pick-n-pluck foam system that Pelican and other hard shell manufacturers use. The problem with the pick-n-pluck system is once you pull out the foam, you’re stuck with that set-up. If you decide to change the setup, your only option is to replace it with a new foam insert. This will set you back at least $30, depending on your Pelican case and size.
