There was a similar special edition out in the US a couple of years back, but due to rights issues, it never made it to the UK. Not to worry, the walnut and basic dark special edition Vitra Hang It All by Charles and Ray Eames is now available in the UK, should you want a variation on the classic theme.
You can still buy the original 1953 midcentury design classic if you wish, but this is a more subdued limited edition, the plastic coated steel frame going darker, while the coloured balls have been replaced with wooden balls in walnut. Slightly more 'grown up' if you like.
Get one while you can, £182 is the price.
