Hi -
It is about 3.5 inches high, 4 inches wide (@widest), and with a opening of about 2.5 inches. Very solid piece of glass, for the size of it.
The bottom does seem to have quite a bit of wear, not sure if that shows up in my photos...and I looked around on it, and I see no Avon mark. Doesn't Avon mark all there things quite well? I do not think I have seen an item by Avon that is not marked. Any older Avon stuff I have here (60's & 70's) is marked well. Avon, (to me), always seemed to make sure all there stuff was marked.
So not sure if these measurements help any (?) Hope so.
TIA
