DIAWALL R-type, black, wall-mountable. - Brand: DIAWALL - Color: Black, 2 sets - Type: R Type - Contents: Includes 2x 2x4 wooden boards and accessories - DIY Type: R Type Thank you for viewing. I considered using it after purchasing and taking it out of the box, but ultimately didn't use it and stored it for about a year. This is a combined listing of 2 sets. How about it for those considering DIY shelving? Although unused, the storage box has some plastic damage. There is no problem at all with the use of the product itself, but if you are concerned, please inquire about the condition of the box before purchasing.
