Paris 2012: get yourself organised with these colourful accordion-pleated document wallets by Copenhagen brand Hay, presented at Maison & Objet in Paris last week.

Called Plissè, meaning 'pleated', the designs include a black cover with an insert of black gridlines on white paper, or grey covers with graduated fluorescent inserts.

The folders come in A5, A4 and A3 sizes.
