When you said Enor sheets, I knew exactly what you were talking about. They had a very unique design and were quite 'stiff', so I could see how some collectors like them. I would be surprised if they still made them, because they contained PVC and a bunch of other nasty chemicals, which can damage your cards in the long term (they cause yellowing to white card stock, for starters). I replaced about 600 to 700 sheets about 5 years ago because of this, and over half of them were Enor. I would have gladly given them to you for the cost of shipping had I not tossed them in the recycle bin.
