Shandon - or whatever they're called this week- sell nylon mesh biopsy bags. These are flat bags, sealed on 3 sides. I have found that if you cut one corner off (ie, a oblong piece with 2 sides still sealed) just a tiny bit bigger than the cassette, you can open the bag, like a book, insert the sample and flatten the bag over the specimen and place it snug and flat in the bottom of the casette. It sems to stay like that through processing (esp if kept the cassette is kept flat in the basket), and is easy to locate against the mesh for embedding.
