We’ve got purple ink refills over at our website (www.mylabmaker.com)
Both fine tip and medium tips (0.8 mm and 1 mm) in both the Echo length (57 mm) and the longer version that fits the Livescribe 3/Aegir/Symphony pens. I really like how these refills write, the purple is a nice color. Check them out at our main site. My WordPress skills have gathered some dust, I’m not up to coding the PayPal links here on the blog for the new refills quite yet.
