18 years old! They’re officially an adult. It’s all spots, broken hearts and the crippling shadow of independence looming large over their heads. I’m sure there’s some fun sides too. What better way to celebrate those aforementioned fun sides than with our delightful range of funny 18th Birthday cards? Whether it’s for a best friend, a son, daughter, grandchild or cards for a niece or nephew we’ve got everything for all those pesky 18-year-old boys, girls, and everything in between.

From funny and offensive birthday messages to quirky and unusual 18th Birthday cards, there’s something for everyone. If they actually wake up early enough to see them. All of our cards are A5 size when folded (14.8cm x 21cm) and blank inside (unless otherwise specified) for you to write whatever bellicose birthday bile that comes to your head.

A coloured envelope best matching your chosen design will also be included with your card (A card lovingly printed on professional 300gsm stock.) Your packaging will depend on how many cards you order, so either a small envelope or large postal box. Both of which are dispatched on the same working day if you order before 3pm via Royal Mail 1st class post.

When it comes to the environment, us and Mother Earth are like that (imagine I’ve got my fingers pretentiously crossed in a symbol of tight-knit unity between two parties) so we are totally committed to sustainability. All our packages are 100% plastic free and all cards and envelopes are made from FSC certified paper. While you’re here, why not browse our thousands of unique greeting card designs for a plethora of different occasions and make sure you take advantage of our special offer: 3 cards for £5 or 10 for £10 across our entire range.
