From the sample photos, it is a review of the difficult to distinguish. The test tube we purchased is a general test tube used in high school and university. For that reason, we thought that the characters "PYREX" and "MADE IN JAPAN" were written in the test tube with white letters. Actually arrived, there is no mention of [PYREX], there was a notation of "MADE IN INDONESIA". The selling origin also became ASAHI GLASS, it became a feeling that bad products were grabbed. However, looking at it, it seems that there have been various things such as existence of patent use and management integration over the past few years. According to the manufacturer site, it seems to be the same manufacturing method as when described as "PYREX", so it seems that it can be used like the conventional product. Since it seems that products with different notation are also muffled in net mail ordering, please purchase acceptable items.
