Tiazza 8Pcs Stainless Steel Flip Top Hinges for Folding Furniture Folding Wings, Sewing Machine Table, Computer Desk, Roll-Top Desk Hardware Accessory

A badly bent hinge arrived; bent so bad it's unusable garbage. Seller did not offer a satisfactory solution to the problem. Now I own 7 usable hinges and 1 piece of junk, that means I can't use any of them because I need a set of eight for 4 doors. Also, these "stainless steel" hinges will stick to a magnet, so there is a high ferric content in them. Therefore I would guess the corrosion resistance is quite low. The finish is quite rough.
