PREMIUM MATERIAL - The chip bag clip uses heavy duty thickened stainless steel material, the steel clip is strong, the spring is very good, brushed metal and does not rust, made of stainless steel, wide enough to fit any chip bag. Sturdy Grip: Our airtight clip has a built-in powerful spring for stronger bite force, and the flat mouth design of the clip effectively isolates dust, moisture. Tight seal: There is a little flat area on the grab end to flatten the bag for better creases and seals. But the inner edge of the paddle handle has some sharp edges, need to be careful.
