Sleeve for Grenade Koozie

Found a great Grenade Koozie but wanted to use it as a Pen Holder when not in use…

It printed nicely but what to do with it when not used as a Koozie? Answer is to make it a Pen Holder…. but there is a hole in the bottom of the Koozie… Hence the Koozie Sleeve to convert to a usable Desk Top Pen Holder… Pull it out when you want to use the Koozie.

Also noticed a nice remix If you want a different look at:
