I was using this without any problems, but I'm selling it because I'm replacing my vehicle. I don't have any specialized knowledge, so I don't know the details. Please be aware of this beforehand. This is a 100L aluminum rear box from ONESTEP. There are scratches, paint剥げ, dents, dirt, discoloration, and rust from use. Please check the images. There are areas that have been covered up with a marker. The one-touch buckle inside the box is broken. Image 9 I bought it a year ago and was using it until recently, so there are no problems with its use. 【Product Details】: 100L Outer dimensions: W56.5 x D52 x H36cm Inner dimensions: W53 x D48.5 x H27cm Weight: 9.9kg Material: Aluminum alloy 【Included Items】 One key is included, instruction manual, washers, bolts, etc. ※The items in the images are generally all that are included.
