Neolab components A5 Ring Binder Notebook-150 X210 mm(pack of 5)

Works perfectly & great value compared to alternatives

These work well with the pen, but we didn't read the other reviews before buying and so were confused when we see videos of multiple notebooks being used at the same time but couldn't get these ones to work. I would say it's a 5 star product if you use one notebook until it's full and then use the next one.
