Oops! When Kim Kardashian teamed up with Kylie Jenner for a Kylie Cosmetics liquid lipstick collab, the sister duo (who could pretty much pass as twins these days, TBH) made one tiny mistake that most customers probably didn’t notice — well, until now.

As viewers saw on the Sunday, June 25, Season 13 finale of Keeping Up With the Kardashians, Kim, 36, opened up about the beauty blunder as she and Kylie, 19, geared up to launch their new line of products.

The problem? Apparently, about 1.4 million tubes of the KKW x Kylie Cosmetics lipstick tubes were made with the wrong shade of pink printed on their caps. While the actual tubes were printed with millennial pink paint drips, their tops were produced with a hue that looked more like deli meat — aka not this season’s hottest color.

Despite the snafu, Kim ultimately decided that she and Kylie should send out the incorrectly printed tubes to save money. After all, isn’t it what’s inside the tube that counts?

Back in April, the Selfish author — who has since released her own cosmetics line, KKW Beauty — took to her official app and website to express her excitement over joining forces with Kylie.

“So much fun shooting with my little twin sissy for our KKW X KYLIE cosmetics collab. Chris Appleton did my hair and Mario Dedivanovic did my makeup using the KIKI Shade from the collection,” she wrote at the time. “Kylie and I both went with sleek, straight hair. Kylie’s hair was done by Tokyo Stylez and her makeup was by Ariel Tejada.”
