304 Stainless Steel Our stainless steel hamburger machine is made of food grade 304 stainless steel, which is not only rust resistant and durable, but also more healthy and safe than the hamburger meat press made of plastic material on the market. If you like clean, you can throw it into the dishwasher without any concern. Easy to UseOur burger machine is ergonomic and labor-saving, both adults and children can easily press the burger meat they want. Just determine the weight of the patty you want, press it into the meat, then press again, and you'll have a homemade patty. Edging TreatmentWe have done a very fine edging treatment on the sharpness of the burger maker, because the stainless steel material tends to be too sharp. But due to its non-stick, so the patty is very easy to shape, so you can enjoy the DIY time of making a perfect burger safely. Excellent ServiceIt's great to be able to make one of a kind burger meat for friends or family at their party.If you have any questions about our products, please feel free to contact us.
