I just recieved some of the blue foam cart filler squares from :police:StricklyEJuice. So far I really like them. Good flavor and reasonable throat hit. I think they are best filled or topped off with a syringe though. Il just make sure to take enough filled ones with me. This is a bad place to get caught with a syringe. My next project is a box mod using an old cell phone battery 3.7 @ 900mah. looks fairly straight forward. Have to hit Radio Shack friday. Anyway if you have ever wondered about the foam fillers I have tried tea bags,polyfill,tulle, and even scotchbrite(don't use). So far I think for effort,reusablility,and function Ill stick with these for a while. Now for that box mod with low res. attys
