Stickers look good but package needs a Stickers Included Card

The printing and packaging look good, but, due to the stickers being piled on top of each other inside the small bag, my customers can't tell what's in the sticker set. The backer card in the bag should be produced with a thumbnail image of each of the included stickers. This is not very saleable like this. We may have to open each pack and create our own sticker set insert card, something that Sticker Mule could have and should have done.
