I am so sick of looking for a good white pen, every pen I've bought so far seems dry or doesn't leave a clear, clean consistant mark. Sometimes on dark pp I have to go over the mark 2-3 times for it to show up and it's endless routines of waiting for the ink to dry because I'm rub the top coat back off with the pen tip.....what pen are ya'll using???
I also Use the Signo White ink pen, I bought some other white pens and they were less expensive but in the end they were a waste of money, Cause they dont work right or the ink looks so light on dark Cardstock.
I have the sakura white souffle pen and it shows up well, too, once it dries. My problem is that I can't always see where I've already written on the dark paper. If you need it right away and you can't find a signo, the souffle pen is a good option, IMO.
I am just extremely dissapointed with other brands I have tried....I've had instances where I get the perfect lo and wanna add some doodles for finishing touches and the pen messes uup the whole lo due to the crappy qaulity.....
I loved Signo at the beginning too but, It started getting very inconsistent. I had to constantly turn it to find the right spot in the nib to make it work. Then it would work then give out. However as far as opaqueness I loved it. It worked on black nicely.
