Quote: Here is a video I remembered with a guy showing off a pb collection in stock pages, which looks pretty decent.
The pages in the album in that video look like vario pages inside sheet protectors. It starts with what look like Vario 4S pages for normal size blocks, but then uses other "S" sizes for larger blocks.
Just my opinion but I would avoid 'encasing' stamps and other paper materials. (I know of no archival library or other preservation proactive which uses sheet protectors of other methods which enclose the item.) The issue is that if you do have any damaging moisture, acids, out gassing, or other environmental issues you will accelerate the damage by trapping it. Let paper breathe. Don
Are you referring specifically to the sheet protectors? What about the Vario pages themselves, if the size is one that completely covers the stamp, or block. In my case, I have numerous albums full of covers in Vario 3S pages, with the covers in sleeves and then placed in the Vario slips. Does the concern about "let paper breath" apply there also?
