Great for writing on dark-coloured items, but keep them well shaken!
All of these pens (silver, gold & white) are good for writing on dark coloured items. I use mine to label my black plug-in chargers, tools with dark handles, and generally anything where using a black marker wouldn't be visible against the background. But they do need a bit of time to prepare them for use, because you have to shake the pen to mix the paint (you can hear the mixer going back & forth after it frees itself & the paint starts to slosh around & mix inside). Then you have to pump the nib, & get the paint flowing. Once you've done this, they work very well. If your pen has been sitting around for a while (especially if stored upright), it could take a very long time to get it working again! I've knocked a star off for this reason, although I don't think there's any solution to these problems, other than periodically giving your pens a shake & writing something on some old cardboard, regardless of whether you're goung to use them or not- just to get the paint flowing.
