The framing is very simple: buckle flap, insert slide - the slide has to be down slightly in the reingeschoben not umknickbaren part - Align slide and then zuclipsen.
The slides can be aligned quickly and easily clean thanks to the prescribed marks. If you have made a mistake, the frames can be easily clipped to a guitar pick again. I am very happy with it for the price. With the associated storage boxes the slides can be stored in a space-saving and, thanks to the CS system safely.
I am very satisfied and can only recommend the frames.
