The package arrived on time and in good shape. The instructions were ok but none of the pieces were marked in anyway. The directions said the R & L panel were marked no so and none of the pieces had a hint or clue as to what it was. Other manufactures put on little stickers that say "A" "B" etc. my husband did figure it out but only because he had put a few shelves together but never from this company. The finished product is very nice and perfect for where I wanted it.
