I really like these fingertip covers, prefer them over the cheap ugly tan ones
from the office supply stores. These are much more comfortable. They are very
tacky, which makes page-flipping or paper-sorting very easy.
Here are the measurements for the SMALL size, just in case it will be helpful to
someone. I took these measurements with the fingertip cover "as-is," meaning
that I didn't flatten them to measure. The base is about 16mm in diameter, close
to the tip is about 11mm in diameter (right before it starts rounding off), and
the length is about 24mm from tip to base.
