I came across the condom brand ONE when working for Projekt6 - an organisation that promotes sexual health among university students in Lund, Sweden.

ONE is the world's largest condom manufacturer and is famous for its playful and colourful round wrappers.

​

Users can take part in ONE's Condom Wrapper Design Contests; the winner gets a cash prize, plus a year's supply of condoms featuring their art, and chooses the health organisation to which ONE will donate condoms to​.

​

I took part in the contest, and won 5 times. And no, I didn't use all of my 5 years' supply of condoms.
