Reddit mentions of Wacom Bamboo - Pen - 2 Buttons

ii think 470 and 480 are cross compatible but not 490.

I got myself the 470 pen and it's working great on my 480.

this one: https://www.amazon.de/gp/product/B0074VS6PY/ref=oh_aui_detailpage_o08_s00?ie=UTF8&psc=1

It should be LP-170-0k, the only difference between them is that this one doesn't have the eraser.

I can link you to this link on amazon where you can order a new pen for your tablet ;)

Yes it is compatible.
I found this offer on amazon this is the cheapest one that I found that is compatible, but I don't really know too many shops in the UK, so you might try searching for a better offer yourself.

i'm french and i don't find it in the french amazon do you think this one can do:
