Galaxy Book 3 Pro 360 S Pen nibs?

Hi,

I’m hoping to establish which replacement S Pen nibs are compatible with the S Pen for the Galaxy Book 3 Pro 360?

The computer doesn’t come with any spare nibs in the box - thanks Samsung, very generous of you! - and there don’t seem to be any available specifically for this device’s S pen.

Can someone tell me which replacement nibs are compatible with this particular S Pen please? Is it the same S Pen as used for another device, one for which replacement nibs are listed?

Thanks in advance.
