For those worried about their shampoo clashing with their perfectly colour-co-ordinated bathroom tiles, German personal care shop Rossmann has launched personalised product labels, which enables people to create and buy personalised bathroom products through Facebook

The Facebook app aims to engage people in a creative process and give them the opportunity to share their efforts with others, while generating brand awareness.

Through the brand's Facebook page, packaging obsessives can click through to the Mein Design app where they can pick patterns, photos and text to have on bottles of Rossmann's Isana bodywash. People can save their creations, and then add them to their basket via the app where they can buy it. Payment is processed through an existing payment system the brand uses to let people upload and print their photos.

The service is being used by over 20,000 people, according to the app's own figures, and there are over 1,290 entries on the site's gallery.

A host of brands create customisable versions of their products in the virtual space, but few have actually let people have their creations for real. Nike pioneered that approach with Nike ID years ago, but it has remained niche, and generally the province of more edgy brands. The stats around this particular app show just how mainstream this has become: 20,000 users and over 1,290 entries is impressive for a Facebook app.
