About the designer preview

FAQ's

  • What are MOO Designs?
    MOO Designs are packs of cards and stickers custom-designed by professional designers and artists. They’re perfect if you don’t have your own design, or if you’re looking for something that’s tailored specifically to your industry. You can add your details and we'll send you a pack that are as professional as you are!
  • I don't like one of the cards
    No problem! You can remove any card from the pack when you start customising them. That way the pack truly represents exactly what you want them to.

    Alternatively, you can build your own fully customised products using our "Full Upload" or "Design Your Own" tools.
  • Can I get these designs on your other products too?
    Some MOO Designs are available on multiple products, but we don't have an easy way to browse them at the moment (sorry!). If you'd like to try and find matching products, we'd recommend searching for the pack name on the relevant product's "MOO Designs" page.
