Simple and modern stainless steel door knob set. - Brand: MIWALOCK - Model: U9HMD-1 - Material: Stainless steel - Accessories: Keys, Instruction manual - Type: Cylinder lock - Backset: 64mm - Door thickness: 33-42mm I mistakenly purchased this with the wrong door thickness. I realized the mistake when I tried to replace it, so I opened the package, but it has not been used. I have written on the box, so I will erase it with a marker before sending. I will attach the shipping label directly to the box. Please refrain from purchasing if you are sensitive to the condition, as this is stored by a private individual. No claims and no returns accepted. Thank you for your understanding. Thank you for viewing.
