Background

Subunit beta of interleukin 12 (also known as IL-12B, natural killer cell stimulatory factor 2, cytotoxic lymphocyte maturation factor p40, or interleukin-12 subunit p40) is a protein subunit that in humans is encoded by the IL12B gene. IL-12B is a common subunit of interleukin 12 and interleukin 23. This cytokine is expressed by activated macrophages that serve as an essential inducer of Th1 cells development. This cytokine has been found to be important for sustaining a sufficient number of memory/effector Th1 cells to mediate long-term protection to an intracellular pathogen.

Beautiful Decorative and Light Weight Shelving!
Color: White
Beautiful shelving. Came with hardware for hanging and a ruler strip template for mounting locations, although the holes did not match up with the shelf holes. Shelves are just the right size for my purpose and also decorative and light weight.

sturdy, solid wood, a couple of blemishes
Color: Black
The shelves are securely packed for shipping. The box for the actual item was dented and smashed at one corner, but the contents were well secured. The support braces (6 in total) had a blemish on one - which I will cover with black permanent marker and face on the inside. The second support, which was packed so one could see the defect upon opening of the box, had a couple of dings on the top of the shelf and a huge notch taken out of the side of the support - which is black and near the top and shouldn't be noticable. I question the quality control to ship out that piece with the serious notch, especially because it was right on top when you opened the box, fully visible. I originally thought it was an angled hole for a screw, until I read the instructions and then realized the others didn't have that notch. The 3 shelves are fine except for the one with a few small dings/dents on the top side. The set comes with dowels, all hardware and so forth. Overall these are solid sturdy shelves.

Color matches photos… but stickers don’t 😂
Color: Wooden, Color: Wooden
They don’t feel cheap & hold a reasonable about of weight considered I have my heavy ass salt rock lamp thing on there. It also matches all my other wood which was what I was really hoping for. One thing that made me laugh is the stickers they included to hide the screws. The color is so off it’s comical. It’s not a big deal though, I am just not going to use them.

Wrong drilling template
Color: White, Color: White
Shelves look nice but the mounting template is the wrong size. I’ve bought other shelves from this brand and loved that it came with the template. It’s not impossible to hang without it, but it’s difficult since a pencil can’t fit through the holes in the shelf to mark the wall. Tried to reach out for product support and got no help. They just send you to troubleshoot on your own information and when it doesn’t work, they just send you back to the start of the same information. Very glad I checked the template against the product before drilling into my wall
