You can use them for example in Snagit, Camtasia Studio or any other graphics software, video editor or office software like Powerpoint or Word. The collection includes 12 different callouts/stamps 350×350 pixels plus shadow. For best results use them on lighter colored backgrounds like white or light grey. Also works very well in combination with light patterns, for example like the White Clean Polygon Backgrounds or The Stage backgrounds.
