I never believed it but my little sister is always going on about "joy" . I always used to use my cheap bic pens, which do have their place but she gave me a full set of Muji pens and they actually made me happy when I used them.

I always wait until the end of september to buy anything if I am going to. It's often less than half price as by then they just want to get rid of them like easter eggs after Easter. I also luuurve valentines day too!
