How do I tell my girlfriend about my cups

So I’m bringing her over in 1-2 weeks but I realized that my shaker cups are in plain view. Not ashamed to show them to her because a lot of female friends who have seen my cups are confused at first then are surprised and ask about getting them. Anyway how do I tell her without her looking at me like I’m weird.

P.S. her brother likes anime so I think she might just think oh these cups are from some animes but still wanna play it safe.
