This product is most commonly called a “star-burst” folder. Star-burst is a copyrighted name, and there are other names, such as “explosion” folder and “pop-out” folder, etc… This style of folder requires die-cut perforating, hand-folding and finally “tipping” into what is most often a heavier stock 4 page “carrier”. In our company we can automatically tip the folder into the carrier if the quantity is large and the size is smaller than 9 inches square. This style of folder is always memorable. I have observed clients while they open and close the piece several times in one sitting. If you want to capture a client’s attention show them a “star-burst folder!
