11 oz./325ml High borosilicate glass. Packaged in a keepsake box. WHAT IS BOROSILICATE GLASS? Commonly known as ‘laboratory glass’, the borosilicate glass found in these double-wal led glass mugs will ensure that you can pour boiling hot water without fearing cracks or shatters. The boron trioxide found in borosilicate glass provides a very low coefficient of thermal expansion, meaning it will not crack under extreme temperatures changes like regular glass. This ultra high-quality glass is often found in high-end restaurants, laboratories, and wineries. Top-rack dishwasher and microwave safe. Designed in Canada Made in China Show more
