Our Cosmic Encounter box insert holds all the components included in the base game, along with plenty of space for numerous expansions. You can tote around your entire collection safely in one box!The inserts also come with adhesive on the bottom, a unique feature to our insert that allows you to fix the insert to the bottom of your box. This is permanent, but makes the insert much more firm and rigid should you prefer, and it will stay in place as you pack and unpack your game components. But of course, using the adhesive is completely optional; there is a liner covering the adhesive, so you don't have to use it if you don't want to permanently alter your box or insert. Having a box insert for your components not only keeps everything safe for transit and storage, but it also speeds up the setup and breakdown processes. We believe our inserts are an inexpensive way to protect your components and help you get the most out of your gaming time.
