Another pen which I believe could substitute for a Dalo is this one
https://uniball.co.uk/uni-super-ink-marker-pna-125/.
Although the distributor is called Uniball, these particular pens (PNA-125) are fine fibre tips.
I've been buying these just as really good, indelible, fine marker pens, haven't yet tried them in PCB making, but suspect they tick the boxes. In the UK, your local Wilko sells them, but as they are made in Vietnam, they are probably available worldwide. In general use, these compare very favourably against the Lumocolour pens.
