The iconic Rotring 600 is on sale on Amazon today for [amazon_link asins=’B00AZWYUA4′ template=’PriceLink’ store=’boingboing’ marketplace=’US’ link_id=’e5771308-7648-4c1d-8ee2-990acba525bc’]. Unlike the 500 (which I also like) the 600 has an all-metal body, which a lot of people prefer. At current prices on Amazon the 600 is cheaper than the 500.
