I had originally planned on using these for finished cards, but it failed miserably at that since my cards always end up a lot bigger. In fact, I was going to return them until I read one of the other reviews who said she uses it for her embossing folders. I tried it and it works wonderfully so now I don't have to return them.
Service from Scrapbook.com was excellent. Their postage rates were very reasonable. As with all ScrapRack products, the flap enclosures need to be redesigned. They don't hold well.
