Harry Styles, Zayn Malik, Niall Horan, Liam Payne and Louis Tomlinson have teamed up with US chain Office Depot to promote 1D+OD Live Love Move Together Against Bullying.
From July, Office Depot in the US will stock 1D-branded notebooks, pens and stickers and nail polish named after each of the boys, reported Sun Online.
A cut of sales will fund an anti-bullying educational programme to encourage kinder behaviour among students.
The cosmetics named after the boys will be flogged as part of the anti-bullying campaign - from lime green for Zayn to indigo for Liam.
