Both good and evil are represented in the image sketch. The top makeup brush is modeled after Luke Skywalker's blue lightsaber, which is passed down to Rey in Star Wars Episode VII. The other brush resembles Kylo Ren's red lightsaber, which is notable for its distinctive crossguard design. The makeup brush set as a whole will include five Star Wars designs, likely following the lightsaber theme.
Unfortunately, the Star Wars makeup brush sketches are not official just yet. Storybook Cosmetics makes it clear that they have yet to receive approval from Disney to produce the brushes. "Time to send positive vibes, and hope @disney & @starwars sell us the licensing to make this happen for you guys!" Storybook Cosmetics added in the caption.
Hopefully, Disney will allow the company to produce their Star Wars brushes. If so, this would not be the first time that cosmetics companies have partnered with the Star Wars brand in order to release a line of products. In December of 2015, just ahead of the Star Wars Episode VII premiere, Covergirl launched a set of Star Wars-inspired makeup. Popsugarcovered the launch, noting that the collection touched on the dichotomy between dark and light within the film series.
The collection continued the dark vs. light theme by allowing consumers to take a quiz to find out if they belonged to the Dark Side or the Light Side. In a set of official looks released for the Star Wars collection, Covergirl created official makeup looks for a set of stock Star Wars characters including a Jedi, a Stormtrooper, and a Droid.
