Send someone special a happy birthday with this card from The Cake Thief

This is a non-personalised design, so you don't have to edit the front of the card. The inside can still be personalised with your own message.

This card can be sent back to your address so you can handwrite the message inside and then deliver or post it yourself. You can also choose to send this card directly to the recipient's address after you've written your own message with our online editor.

Once you click through to personalise your card, our online editor offers you the chance to edit the text you add inside, with the font, size, colour, layout and more.

Further customisation options include the choice of four different size options from small (A6) through to giant (A3).

All our greeting cards are printed using high-quality, recyclable card, ensuring they take pride of place on the recipient's sideboard.
