This Muji stuffed giraffe is made from the leftover cotton yarn that would have been thrown away at the end of a production run, so it's not technically "re-used," which'd be slightly gross, but "reclaimed" or "re-scued" which is environmentally considerate and quirkily unique.
With the giraffe priced at £7.50, Muji may have even passed a scintilla of those savings onto you. But not much. Re-used yarn-covered cows or elephants are less, £6.95. [muji.co.uk]
