Promethean panel pens

[synaesthesia]

Might be a daft question, but I'd rather not waste money trying my luck!

 

Promethean pens for activpanels - does it matter which we buy? Some appear to named or sold specifically for models like the Platinum or Titanium, V7, V8, V9 etc but I can't imagine there would/should be a difference. Can anyone confirm please?

(Just thinking of a few of these for our mixture of boards - https://promethean-reseller.co.uk/products/promethean-v7-nickel-pen )

I don't think it matters, we've got some newer titaniums and some older version (not sure which) but the same pens seem to work on all of them.
