Polarity of tantalum capacitors

Howdy all,
Recently got back into basic electronics and have started building kits. Been building a kit that uses tantalum capacitors and it notes that polarity orientation is very important. The question I have is: is there some un-published indicator of how polarity is indicated on these tantalum caps? I've been over these things with a microscope, even bought new ones, but other than the values & manufacturer, I can find no obvious sign of polarity. Leads are the same length and not marked. What am I missing?
Thanks in advance for any help.

I've had a google around, but all I can find are comments like;

The electrolytic and tantalum capacitors are polarized (polarity sensitive), and are always labeled as such. The electrolytic units have their negative (-) leads distinguished by arrow symbols on their cases. Some polarized capacitors have their polarity designated by marking the positive terminal.

Wait, I switched to image search. Does this help?




It looks like, when you are looking at the printed markings, negative is on the left, and positive on the right.

I was beginning to think that me'self after looking for a bit, but was looking for confirmation, or at least someone else to blame when I blew them up. ;)
I'm also waiting on the kit-maker to respond to the question as well.
Ironically, the kit in which the capacitors are giving me so much grief, is a capacitor meter.

Yes, that is how I understand tantalum caps to be labeled...
