Reading it from up to down, it's Alpha Phi Omega, which is the service Fraternity. I was in Omega Phi Alpha, the sorority, and had to get the charm somewhere else because the letters bone way is for the frat and other way is for the sorority
Change the Name!
Alpha Phi Omega is a National Co-Ed Service FRATERNITY, not a sorority. So the name of this charm should be changed. Otherwise, it's super adorable!
