This collection includes hand-picked, age-neutral cards suitable for an adult 40th birthday; these designs do not need a printed number to mark the occasion. Check the individual product details before choosing your favourite. In your message, mention a shared memory, something you admire about them, or a wish for the year ahead. You can make the milestone explicit with a simple “Happy 40th birthday” and then add the words only you could write.
