Muji Aluminum U-Lock, Gray, New, Unused This item was found at home. It has not been opened, still in its plastic case and paper backing. I will sell it to someone who can use it. *Please refrain from purchasing if you are concerned about the fine details of the condition. Approximate size: Bar length 13, total length 12, U-shaped inner side 5, lock thickness 1.7 (cm) Comes with 3 dimple keys. I used a similar silver one before, and it was quite sturdy. Considering the keyhole etc., I think it's quite secure as a security measure. Stored at home, shipping included. No smoking environment, no pets. No returns or exchanges, please.
