Being from Sao Paulo is a plus. There is a lot of money and a lot of good glass in Sao Paulo. Some of the best glass is bought by people there. Sellers in the area often offer things that I don't see in the USA, but I can tell they are good quality. The products probably differ because of the different tastes of the importers at the time. The vase in the listing seems to be made carefully, but I would have liked a better look at the rim. The angle of the pictures is rather clumsy, making it look like bits of latticino continue through the clear glass. I figured out that we were really seeing the latticino on the other side of the base. I wrote the seller to ask how heavy the glass was, but he/she was apparently away from the vase at the moment, so told me he/she would try to get back with the answer.
