Admittedly, historically, I have purchased various types of after factory (gotta be careful with OPsec, here) valve stem covers, and even if those green and red plastic ones are somewhat novel and provocative, I have seen green and red tastefully (not that having penises would be exactly tasteful) presented within a aluminum form factor. .. I agree brass would be nice too... but then I doubt that brass can be done in green or red - and that would be o.k... too.. for sure, having balls is also  better thing - especially if the item in question is presenting as male.. (cough cough.. all bulls should have balls, even if they are make believe bulls, otherwise by definition, it is not a bull.. and what's wrong with bulls, anyhow?.. we against bulls?  or only certain kinds of bulls?  I am against ball-less creatures claiming to be bulls - just saying)

Furio Tedeschi cares not a whit about the criticism heaped on his robo-crypto bull statue, which was unveiled in Miami on Wednesday during a large cryptocurrency conference. The chrome-and-fiberglass work pays homage to Wall Street’s bronze version ...

...

But Tedeschi is wondering the same thing as many others. What happened to the bull’s—erm—testicles?

When he submitted the statue’s design to its corporate sponsor, Tradestation, he included that anatomy, he says. “I’m sad to see that they removed them,” Tedeschi says. “I’d designed some huge, mechanical balls.” (Tradestation neutered the creature to ensure it wasn’t seen as promoting a male-focused financial industry. “Prosperity and wealth shouldn’t have any gender,” says Marco Carrucciu, a vice president at the online brokerage.)
