Review on Stay Fresh And Organized With Bayco'S Glass Storage Containers - 9 Sets Of Airtight Meal Prep Containers In Blue by Edwin Black

Real Borosilicate glass, as PYREX used to be. How many people know that today's "pyrex" is not only a "cutsie-poo" logo but means that the glass is now junk soda-bottle (green) glass that has only been "tempered". It will not withstand large temperature changes unless very slow. Only a Capital "P" signified genuine PYREX, and that current producer has been duping the public since 1989! Today BAYCO is still using quality Boron glass (clear) and at a great price! Highly Recommended! Buy from Genuine producers, reward an honest company and don't waste your money! Look at the thick edge glass to see the true color!
