Just as I was preparing my Kodak glass negative carrier I found a Zipper Glassless Carrier. 5x7 negative carriers are hard to find and expensive, this one was $25. and holds the negative tight as a drum. Does anyone have one or know anything about them? I had never heard of them before just recently. I'm using it with my Durst 138 5x7 enlarger.
