Find me in Philadelphia

I got a lot of emails in the past few days of people asking what's the best pen for the rocks. Right now I'm digging so much the @tombowusa Mono Twin Permanent Marker. So easy to do calligraphy on my #wordrocks . Aren't they beautiful?! This set is flying today to Philadelphia thanks to @tristansiljander
