A nice surprise - these are easily the equivalent of the most commonly-cited US made extrusions. The 4040 size is very strong and the pieces are individually wrapped in plastic to keep them cosmetically perfect."Clean" in the headline refers to the quality of the extrusion itself, as well at the cuts. No scratches, gouges, dings, waves, etc. Excellent quality. There were some chips and debris in the packing, however. While it didn't damage the pieces, they really should have been properly cleaned before shippingShipped fast and decent value. Gets a recommend from me.
