FYI,

I don't like these things.  I found that when ECC (endocervical curettage)
specimens were filtered through them, the specimen would be next to
impossible to retrieve for embedding.  In addition, when prostate or
cervical biopsies were placed in them for processing, one had to be very
careful when opening the bag (they tear open quite easily, which is good).
But, if the end you were holding with the forceps suddenly slipped off, the
specimen would catapault somewhere and the search would begin.  Give me lens
paper any day.
