So, I'm looking for those things that are the size of 12g CO2 cartridges that fill up with propane/green gas.
I'm either totally imagining these, and they're just something I want to exist, or I heard of them somewhere.
If you know what they're called, post up.
If you know where to find them, post up.
If you know I'm wrong, tell me they don't exist, post up.
If you're a Snowball, post up.
If you just want to increase that postcount, you know what to do.
