We have redesigned this French fry knife, using a large amount of stainless steel and aluminum alloy materials on the body, making the machine very sturdy and durable. We have also redesigned the suction cup to firmly adhere to smooth surfaces. We focus on the quality of our products and the user experience, and have optimized our product design multiple times to make it safer and more convenient to use. Reminder: For the first use, apply a little food oil to the four sliding rods to make the machine smoother when pushed! If a few drops of water are dropped on a smooth operating table, the suction cup will adhere more firmly.
