As reported by others are the wooden elements in rough-sawn state, so you should remove before mounting again with sandpaper Splitter etc. in order to not infringe on the use. Fully assembled is the shelf but really stable and does the job perfectly. Little low, I found that the shelves or cross members (on which the bottles are) are on the front sides not pre-drilled. If you want to mount the floors horizontally, you should frontally short drill holes, or tinker a lesson. All in all a good buy!
