Hey. I'm Emma and I decided to buy the Puffco Pro pen. I'm really excited about it don't know much about how to or where to buy the wax, how to measure the right amount to put in the chamber, and how to clean it. I tried my friend's pen and I liked it so such I wanted my own. Unfortunately, I no longer have this friend to guide me. So I was hoping someone here can please help me? I'd appreciate it.
