Tattoo markers?

[somethingrandom]

Bic now offers a line called BodyMark, temporary tattoo markers that are specifically designed to be safe for skin.

I'd be very curious to see how well/if they work on TPE and/or silicon. (I know, they aren't skin, so the ink may react quite differently).

Here's the official website:

Will probably bleed on TPE and not even stick on Silicone...

That's a shame, but I trust your expertise. Thanks for the input.
