Enter the turnstiles.

Legendary rap group Wu-Tang Clan are promoting their new Hulu series in a place straphangers can’t ignore: their MetroCards.

The group’s new signature cards feature their signature “W” symbol on a yellow background. Today, 250,000 of them were quietly distributed to 10 subway stations, SILive reports.

Twitter became aware of the collectible cards with a tweet from the Clan’s official Twitter on Wednesday.

“Who wants one?” the Clan tweeted with a photo of the card, to the tune of 4,100 likes.

The MTA confirmed to the Advance that the South Ferry/Whitehall terminal’s machines have the cards, and an unofficial list posted to Twitter claims that machines at Chambers St., Atlantic Ave-Barclays and Bowling Green, as well as six other stations, do as well — or did, at one point.

The 10-episode Hulu drama, “Wu-Tang: An American Saga,” premiered on September 4 on Hulu, with the next episode set to drop on October 2. The series is based on two novels written by RZA, the group’s founder. The books chronicle the group’s rise from the streets of Staten Island and the release of their iconic album “Enter the Wu-Tang (36 Chambers).”

The art cards are not, however, available at the Clan’s native Shaolin — even though MetroCards are needed to ride buses and the borough’s above ground railway from the ferry terminal.

And while Wu-Tang is forever, the swipe itself is far from it. The MTA has already begun rolling out OMNY, the system which will replace MetroCards as a system-wide fare payment system. MetroCards are expected to be phased out by 2023, officials say.

Since their launch in 1993, MetroCards have become a canvas for many artful promotions for everything from the remake of David Lynch’s “Twin Peaks” to a David Bowie exhibit at the Brooklyn Museum.
