I have the following Air-Tites available. I would prefer to trade for chip or chips...would also just sell them outright. I would also prefer to sell or trade them all to one person. Not looking for much...e-mail with offers.

13 X 39mm black foam ring
10 X 43mm direct fit
3 X 43mm black foam ring

all of these are like-new, no cracks.

I will pay for shipping on my end of the trade.
