Steve, you wrote "Rolodex uses PVC plastic which has harmful long-term effects to anything it holds. This is well known among coin collectors who saw their coins destroyed over the years" Yes, but coins are metal and slot cards are PVC, so how is PVC going to hurt PVC.

and "I use Avery pages myself because the plastic is archival quality and they are cheap." Cheap is the word for it, we found that the pockets rip easily, trying to change card positions because of later finds, wasting a whole page - that's why we chose the better Rolodex Business Card Kit for our pages, no problems at all.
