Go Cyclones!! What better way to show your Iowa State spirit, than with a custom created and NCAA approved Mailbox cover! Great for either metal boxes or plastic or even wood - as long as they are standard in size. Our overlaminated, heavy duty magnetic material makes this Mailbox cover a long lasting investment. Make sure you check out our other designs to find the one that is just right for you! To convert to a non-metal Mailbox, just use double sided tape on the bottom (not included in purchase). Works great!
