I might get some of those for my Rickenberger, as the neck is a bit scruffy and I can't see the dots.
(The whole feel of the bass is that the neck has shifted away by 2 frets, compared to my Rics and others, so I can't play it without looking.)
Farnell's price +shipping +VAT puts me off as a retail buyer, but I see they do free shipping over £8, so that's good (still +VAT, though).
Whilst browsing, I noticed this pot; interesting form-factor, though it's not a guitar-spec model.
