PVC is poly-vinyl chloride. Even though they are supposed to not contain PVC, they might have some traces of it. If you want those flips, change them monthly and keep an eye out for environmental conditions. Otherwise, 2x2s are better and require less expense and maintenance.

You want non-plastic flips for long term storage. They 2x2's are suitable, but not something that I consider suitable for my needs. I use Saf-T-Flips. The 2x2's have a very thin mylar film that becomes brittle over time and are susceptible to breaking. Also, the use of staples to close the flip has caused damage to other coins as the thin mylar film does not protect the coin's surface when it comes into abrasive contact with other 2x2's. Think of dealer's inventory in the red sleeve boxes. They are packed full of 2x2's. The 2x2's are constantly being shuffled in/out as customer's leaf through box. The staples have caused additional damage when they inadvertently come in contact with other coins.
