I’m using this supercute Hello Kitty Momiji cup for holding pens, because I don’t want to mess it up with liquids! You can find more awesome Momiji Hello Kitty stuff at http://lovemomiji.com/. The last picture shows the inside of the cup where there is a cute Hello Kitty surprise! 🙂

Cute! I like how it has a slight 70’s vibe to the design, great find.
Thanks! I like it too! 🙂
