【Tungsten Carbide Roller】This glass cutter uses a tungsten carbide tip roller, making it suitable for beginners to professionals. 【Oil-Filled】The oil-filled design allows oil to flow automatically, providing consistent, even cuts and a smooth feel. 【Perfect Size and Weight】The size is suitable for men, those with smaller hands, and women, allowing for comfortable use. The transparent body allows you to see the remaining oil, and at approximately 45g, it's lightweight, ensuring fatigue-free and stable use. 【Includes 2 Replacement Blades and a Syringe】Even with a tungsten carbide roller, the tip will eventually wear down. This set includes two replacement blades and a convenient syringe. You can use your favorite tool for a long time. 【Versatile Use】Glass cutters aren't just for glass. They can also be used on mirrors and tiles. The cutting thickness is 3-12mm. Depending on your skill, you might be able to handle slightly thicker materials.
