This is a Photoshop mock-up template to place your brand-/ bandname/ logo on a bunch of guitar player plectrums. The template uses Smart Objects, you just have to edit the smart object layer, paste your design  and Photoshop updates it on all of the plectrums. The Photoshop file is fully editable with organized layers, so you can edit and customize it to your needs.
