Pyrex glass rods (Iwaki Glass) Clear Diameter: 1cm Length: Approximately 1m50cm - 6 rods Approximately 1m40cm - 1 rod Approximately 1m34cm - 1 rod Approximately 1m - 1 rod They are long, and I cannot cut them, so I will send them as is. The tips look brown in the photo, but this is due to shadows. They are heat-resistant glass, so they will not melt unless using an oxygen burner that reaches high temperatures. Thank you for looking. #BorosilicateGlass
