These are perfect to use as advertising for your band or brand. People tend to ignore or throw away flyers but they are more inclined to keep a guitar pick.
All picks must be of the same design but if you choose double sided print then both sides can have a different image.
These picks are interned more as a novelty or promotional item but they can be used to play the guitar. The image will fade at the point where the picks touch the strings but the print is generally very durable.
