I would buy air-tites if coinedbits.com sold them. I plan on buying 5 coins once I move to my college dorm next weekend.
I think coinedbits might be looking to order some in bulk to offer for sale along with the coins, but you'd better wait for them to say it.
+1 if coinedbits.com sold them. Love to have them in air-tites...
Cheers,
Kermee
