【Product Description】 Pyrex was born in 1915 as a household heat-resistant glass product by Corning (founded in 1851), a long-established glass manufacturer that also supplied Edison's incandescent light bulbs. It was named "Pyrex" because the first product made was a pie plate. This is a Pyrex Canada Delphite Blue refrigerator storage container. Size: 8.6cm (length) x 11cm (width) x 8cm (height) * With lid 【Condition】 There are scratches on the lid (photos 9 and 10), but otherwise, there are no noticeable signs of deterioration such as scratches or stains from use. The watermarks often seen in this type of product are also present in this refrigerator container (photos 4-8). Since industrial products of the time relied heavily on human hands, the quality of each product varied, and now, more than half a century after its manufacture, it is a vintage enjoyment that lives on as a unique characteristic.
