Wish a Happy Birthday to a special Sister with this card from our inhouse designers at Funky Pigeon.

Personalise the cover with a name.

This premium square card is printed using our finest card which features a unique, high-quality matte finish for a fantastic result that looks and feels great. This premium card stock is made from 100% FSC® certified, environmentally friendly ECF (Elemental Chlorine Free) 300 gsm board for a card that really stands out.

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

Photos can also be added inside this card, with our various inside template designs. You can add images to the inside left, inside right and even to the back of the card for that extra surprise.

Once you're finished creating your personalised premium square card, you can have it delivered straight to their address on a day of your choosing, or send it back to your address if you'd prefer to deliver it in person. You can even add a "Do not open until..." message for the recipient if sending in advance, so they know not to open it yet!
