A video on TikTok has gone viral for showing off a set of paper Starbucks cups that appear to be inside out.
The clip, posted last week by TikTok user @sereniteaboyyo, who goes by Serenity, starts by showing a stack of white paper cups.
Serenity then picks up a few of the cups and reveals that the Starbucks logo and other markings are on the inside, rather than the outside.
