HAPPY SPARKLY RAINBOW FILLED MAGICS are most likely the best elements possible to wish someone well on the day of their birth. I'm sure there's even, like, science to prove that or something. AND SCIENCE DOESN'T LIE! Do your friends a favour. 

This is my illustration, and is printed on 300gsm 100% recycled card. Each rainbow on each card has also been HAND PAINTED WITH GLITTERY GOODNESS (detail in image 3). Card measures 105x150mm, and comes with a 100% recycled craft paper envelope and is sealed in a cellophane bag.

Card is blank inside.
