What better way to test your beauty products than by giving them to your family?

Kylie Jenner, whose plumped out pout is the envy of all her fans (and one of Kris Jenner’s biggest regrets), is giving fans a sneak preview of her upcoming cosmetic line for lips by modeling it with Caitlyn Jenner. In a new Snapchat video shared on Monday (Oct. 26, 2015), Kylie, 18, and Caitlyn, 65, show just how versatile the new lip kit is by testing it on themselves.

In the short clip, the two are seen wearing the same shade of matte nude lip stain.

“Kylie Lip Kit preview,” Kylie, wearing a mint green wig, tells the camera.

“Okay, we have the same Kylie lip stuff on, see?” Caitlyn quips.

As previously reported, Kylie is currently working on her own beauty products line solely focused on the lips so her fans can replicate her signature look without damaging their own puckers.

“I’m going to keep that a secret, but it’s a kit and I am super invested,” told Yahoo Beauty in September. “I have been going to the factories, making the shades perfect, because I’m super particular about my lip color. I wanted to make three perfect shades to start off.”
