Caroline Mickler is growing The Moomins programme, adding Copywrite Designs to create a line of gift stationery.
The range will include notebooks, pencil cases and pocket organisers, plus to-do lists, notecards and sticky notes.
All items will be illustrated with pictures of the Moomintroll and the word Moomin against a pink, blue or turquoise background.
"We are delighted to be able to work with the Moomin brand, not only because of its iconic appeal over many decades, but because its elegance and charm make it perfect for gift stationery that is both striking and original," said Richard Mason, commercial director at Copywrite Designs.
Caroline Mickler added: "The quiet charm and enduring appeal of the Moomins lend them perfectly to a range that is both light hearted and beautifully designed. I feel sure that this delightful range of gift stationery will appeal both to Moomin fans and to those who simply love unique and attractive design."
