Very small
I bought these for my friends who are all turning 50 this year but didn't realize how small they would be, which is a little bigger than a quarter.  After I received them I went back to my order and it does state the size, so that's my fault.  They seem to be of good quality, however, if you're buying them, especially for women a little older, they are hard to read because they are so tiny.
