A personalised 21st Birthday Card from CardMix.

Customise the Name to create a unique 21st birthday card.

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 uncoated premium card stock is made from 100% FSC® certified, environmentally friendly ECF (Elemental Chlorine Free) 300 gsm board for a thicker card that really stands out.

Personalise the inside of your card with your message using our text editor with our spell check and font and colour choices. You can even scan your handwriting into the card for a special touch.

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!
