Mahle Original Premium Piston Ring Sets
Mahle Original piston ring sets are designed to be installer-friendly. They are pre-lapped to seat immediately, virtually eliminating break-in time. Ring materials and coatings, as well as ring tension, are all optimized for reduced friction and extended life in each application. The compression rings feature a barrel-faced contact area for more efficient compression and CNC-controlled gap chamfer to optimize compression and reduce blow-by. Intermediate rings have a reverse twist design for better groove side sealing, and taper race machining to enhance contact. The CP-20 oil ring assemblies feature a 20 degree ear angle, an exclusive feature that provides the best possible side seal against the cylinder wall, and a special chemical polish on the oil ring expander offers enhanced oil drain back. Mahle Original piston ring sets provide unmatched quality and ease of installation, making them the rings of choice for today's engine builders.

Worth it if you're a figure/doll collector!
Color: A. Black Board & Black Brackets, Number Of Shelves: 4, Size: 16-inch, Color: A. Black Board & Black Brackets, Number Of Shelves: 4, Size: 16-inch
I ordered these shelves to display my figures and dolls, and I love the way they look! I ordered 2 sets of the 4 pack in black with black hardware. After looking at reviews, I took the jump and bought them and don't regret it!
TL;DR: Listing is accurate, don't use the paper measurement thingy, quality is what you'd expect for the price, doesn't come pre-drilled, easy enough to put together, over all worth it if you're looking for smaller, decent quality, decent price shelves especially if you display figures or dolls.
1. Listing: They are accurate to the measurements! They're only 5.5 inches deep, so there isn't much (if at all) any room for layering. They do feel small, but the listing is accurate!! Mine are paired next to each other to create a "longer" shelf. DO NOT use the paper measurement thingy. Another review mentioned it was un-even, and after holding it to mine, yeah, it was off. I'd highly recommend a stud finder, small leveler, and a white gel pen or marker to mark where to drill if you do.
2. Assembling & Mounting: The shelves didn't come with pre-drilled holes for the mounting options because it was easy enough to screw into. I will warn you that the small screws only came with a singular extra, so be careful about losing them in case it's the same for you... I'd highly recommend doing this on a FLAT surface. I stood the shelves on the side that would be flat against the wall and set the brackets against it. I put one screw in on each side (both brackets have 1 screw to hold them where I want) then I laid it on its top and tightened and added the other screw. I may have done more work than needed, but none of mine are leaning forward or backward super far. I used the "load bearing" mount simply because I like the look but if you intend to put books, I would do the "no drop" design and possibly get some other L brackets for more support since books can get heavy. PLAN WHERE YOU WANT THE BRACKETS if you intend on doing the "load bearing" design or adding any more brackets.
4. Quality: I kind of expected the wood to be a bit thicker/more sturdy feeling, but upon realizing they didn't come pre-drilled, it made more sense. THEY CHIP AND SCRATCH EASILY. If you're like me and don't really care as long as you cant see/don't notice it, then this isn't any concern but they may come damaged cause some of our mail couriers aren't the best. If you stick them in the corner like I did, please be careful about it slipping! I accidentally dropped the second one from a 21-inch TV stand after adding brackets, and the corner chipped (yes, I measured). The hardware is standard screw quality, and the brackets could be better. After reading the broken bracket reviews plus the price, I honestly wasn't expecting much, but they aren't too bad! You can always replace them with another one you like!
5. Overall: I'd say these are worth the price and I see why "customers usually keep this item"! They were easy enough to mount, even if you aren't the handiest man out there. I'd definitely recommend these if you're looking to display anime figures or dolls like I do! They're nice for adding vertical space without sticking out of the wall too much! Definitely good for smaller spaces! I'm very happy with this product and will more than likely return to this listing if I want some decent and affordable shelving!
Thank you for reading my review, Im usually hesitant to buy online so I hope it helps you decide if you wanna buy these shelves as well!
(Also, in case anyone is wondering the layout, the longest shelf will be 1, the middle length will be 2, the shortest length will be 3. It's the last image of the review!)

Love these shelves! They are sturdy, easy to install, and perfect for organizing bathroom essentials.
I used them above the toilet, and they fit perfectly in a small space. They helped me keep things organized while also adding a modern and decorative touch.
Great quality and very functional. Highly recommend for anyone looking to upgrade their bathroom without taking up extra space!

Pirate ship shelves bathroom - perfect!
Color: C. Rustic Brown Board & Black Brackets, Number Of Shelves: 4, Size: 16-inch, Color: C. Rustic Brown Board & Black Brackets, Number Of Shelves: 4, Size: 16-inch
Love these shelves! I ordered them to match my "pirate ship" bathroom theme. They are solid and the wood is finished on all sides. My husband had no issue installing them. The only thing he found odd was the 15/64 drill bit it recommended. That's an odd size. The shelves look great and hold all on my stuff really well!

Amazing little shelves
Color: G. Black Board & Gold Brackets, Number Of Shelves: 4, Size: 16-inch, Color: G. Black Board & Gold Brackets, Number Of Shelves: 4, Size: 16-inch
I love them! I use them in my nail room for clients and to hold my product. They are sturdy enough to put phones, keys, and their water bottles on. Being able to hang them in different ways is awesome for different aesthetics.4 different sizes. Easy to put together it came away with all the hardware you need. My only complaint is that the wood fills rough so not really able to dust them. I have to fix that
