Airtite Holders, 2x2 Flips Or Coin Albums? And Why?

Personally I use 2x2 although for my better coins I just love the Coin Edge Holders. You see the edge it is sealed at two points around the coin and around the outer edge. Note: larger coins only seal around the coin.

Was it a Harco Coinmaster Album? If so, then you made a good call to dump it. They had PVC pages in them with PVC slides the coins went into. Not a good place for coins. They later replaced the PVC pages with a different type, but they were very brittle and did not last long.

some of my coins are in 2x2's but most are in dansco albums then stores in vaccum sealed bags

None of the above!

I just did a back page and GONE! Crap!

Here we go again. I just bought 500 Collector Safe black foam white backed snap closing 2x2's for my best 500 Jefferson and some Buffalo nickels.
They do come with some cheesy stickers that are for date and grade but I won't use those. For the most part only about 1 in 25 is either scratched or has some defect on the white backing.
That's OK, but hope the ratio gets better. I'm saving them so that I can maybe get an exchange later from the dealer.
I am wondering if anyone else has used this type of holder and do they live up to the name?
I have used the standard white 2x2's that are stapled closed for storing my 30 plus year accumulation. A small number of my nicks have been invaded by small amounts of green/brown verdigris, and some others have become hazed or carbon spotted. I have extras or will upgrade them for my main set.
I just hope these holders will not react to my coins after the transfer.
I've done 100 or so thus far and they look awesome in these holders.
I wear a spray painters nose/mouth facemask and a dollar size cello windowed 2x2 to squeeze and manipulate these into place. This is very time consuming, but I will be glad when my collection is lined up back to back in storage boxes with some anti oxy packets and in my safe.
Again, has anyone used these? I don't mind toning, but corrosion and reaction to the foam or plastic has me very concerned. Some of these coins were so much fun to find and I'd hate to see them get ruined. here's a link to what these look like.

I have used 250 of these, so far.
I kinda wish they were black foam on both sides. One side is white and it is difficult to get my coins in them to show both sides completely. Hard to explain. They don't come with instructions so I wondered if you should push the coin through the white side ( paper ) first until it is just flush. With some patience though they can look pretty good in there. These are not as good as a slabbed coin insert from PCGS or NGC. They show the coin so nicely, these seem to have the coin tilting one way or another from the black side so that is about all I have to say about them that is negative besides that an average of 1 per 25 is either scratched or has an adhesive stain on the paper.
These plastic 2x2's will fit in a normal 2x2 box though which is what I will use instead of the white boxes they come in that is shown in the picture. Those I will save and use for shipping lots I plan to put together and sell of my duplicates.

I was just wondering mostly ... if anyone had any negative storage issues with these holders on the appearance of the coins, such as, carbon spotting or corrosion or reactions with foam or plastic.

I have to say all 3. I use airtites for proof silver because I like the presentation and have to believe I'm storing them safely. I live in Florida and, so, have to take extra care. I also use plenty of 2x2's and store them in intercept boxes. Finally, I love albums as they show off complete sets nicely.
