21st Birthday Card In Numbers

Twenty one or 21 - a triangular number, expressed here on this different personalised birthday card for a 21st Birthday.

Numbers, eh? Well, for your twenty-one-today year-old they might like to know that 21 is a triangular number (not that they'll care much) but at least you can impress them with a card that's a little different from the norm and will allow you to remind them that although they are now an adult, you're still smarter than them.

A bold, typographic card with a nice screen-print effect.

Our cards are printed on 350gsm card and packed in a cellophane to keep it in tip-top condition!

Avaliable in pink and blue
