San Francisco-based Coveroo has added Marvel Entertainment and the National Basketball Association licences to its range of custom replacement mobile phone covers.
Coveroo uses a HighColor process which uses over 65,000 colours which it promises won't fade, rub off or peel.
The licensing agreement with Marvel initially includes characters such as Captain America, Spider-man, The Hulk, Thor and Wolverine. Meanwhile, the deal with NBA means fans can choose from all 30 team logos and current superstars.
"We are excited to offer Marvel fans a new and innovative way to connect with our characters," said Jamie Kampel, director of licensing at Marvel Entertainment. "Through a simple yet high quality device personalisation technique, people can now showcase their favourite characters and new movie releases in a uniquely visual way and on a device that rarely leaves their side."
In addition to Marvel and NBA, Coveroo has an existing library of officially licensed artwork consisting of over 1,000 different designs.
"Our goal is to put the personal in personal electronics," said Coveroo CEO, Karl Jacob.
