Can I use any refill?
For Livescribe 3 smartpens there are various options for which ink cartridges you can use, but you CANNOT use ink cartridges designed for the wifi/Echo/Pulse smartpens as they are a different size. For more information please see 50010 - Livescribe 3 ink cartridge compatibility.
For wifi/Echo/Pulse smartpens, only Livescribe ink cartridges can be used. These smartpen refills were designed exclusively for the wifi/Echo/Pulse smartpens and no other manufacturer's ink cartridge will fit.
In the U.S. ink can be purchased in our online Store at http://store.livescribe.com/.
Outside of the U.S. please see http://www.livescribe.com/int/smartpen/retailers.html.
