I think this is great for revelations but the glasses just aren't consistently in good quality.
I bought several of these because it seems like it would be great to have extras.
When I actually received them, they were curved different. So each pair actually didn't fit
right at all. One side was always on even because of the way the glasses were shaped.
The
quality of the revelations also differs from glasses to glasses. Some have ink dots when you
actually reveal them.
