Unhappy Tantalum capacitor markings

Hello, I need some help.
I can't identify polarity of tantalum capacitors I've bought. Markings look like this:

   |
1  |
35+

These two "vertical minuses" are thicker than + sign, so I'm not shure what's relevant, + for +, or vertical minuses for - like at elco's. Leads are the same lenght.

I know the way for shure identification, but I don't want any firecrackers and it's a damn sunday

Thank you.

Electrolytic caps have the - lead marked, tants the + lead.

The plus lead is the one marked +. The other two lines are not minus marks.

The plus lead is the longer of the two leads, if they are different lengths.

In the picture, the lead on the right is the + lead.

Check out this reference to learn how to connect tantalum capacitors:

Tantalum Capacitor Polarity Markings

It's highly likely that you ignore the vertical - signs and that the plus sign shows the anode of the capacitor.

Usually the longer lead is the positive end of the cap.
