I thought I might give the air pot thing a try. I would like to see the pot(s) first to make sure it is the real air pot and not the knock offs. I understood from what you wrote that you want .50 each for them. Anyhow, let me know if you still have them and how to contact you and we can go from there.
Here is an image of the same airpots I'm selling
They are the original with the green "smart pot" tag. I purchased 100 direct for my own use so I can vouch they are the real deal.
I was asking 1/2 a BTC originally, but the price has gone up now so I'm only asking .25 BTC each plus shipping. Private message me and we can go from there
