Suitable for upper-level undergraduates, this accessible approach to set theory poses rigorous but simple arguments. Each definition is accompanied by commentary that motivates and explains new concepts. Starting with a repetition of the familiar arguments of elementary set theory, the level of abstract thinking gradually rises for a progressive increase in complexity.A historical introduction presents a brief account of the growth of set theory, with special emphasis on problems that led to the development of the various systems of axiomatic set theory. Subsequent chapters explore classes and sets, functions, relations, partially ordered classes, and the axiom of choice. Other subjects include natural and cardinal numbers, finite and infinite sets, the arithmetic of ordinal numbers, transfinite recursion, and selected topics in the theory of ordinals and cardinals. This updated edition features new material by author Charles C. Pinter.

Pieces missing, poor instructions, would not buy again!
Let's start with the good news: I did, eventually, get the shelves hung after a trip to the hardware store and some trial and error.
Now for the bad news:
* One of the screws holding the brace to the shelf was missing, making the shelf wobbly before I even hung it.
* The directions for hanging the shelves show a different anchor than the one that comes packaged with them. This anchor will ONLY work in sturdy drywall and it's going to leave a huge hole behind.
* The directions tell you to flip the shelf upside-down to position and mark the screw holes, BUT that means the sides of the shelf are reversed, and the hole positions do not match on each side. So if you start hammering or drilling based on those marks, they don't align and now you have extra holes in your wall.
Honestly, I regret buying these and wish I'd just chosen a free-standing shelf instead. But I made it work for me, so I guess there's that.

Solid Floating Shelves 🛠️🏠
Color: Black, Number Of Shelves: 4, Size: 15.7in
I have installed four sets of the black floating shelves in my office. They are made of high quality materials, featuring a sophisticated black woodgrain finish with a natural texture. Supposedly, each unit can handle up to 22 pounds, though I would not recommend testing that limit with your vintage bowling ball collection if you value your flooring. They are awesome.
The value is good for a set of two. Each shelf measures 22x7x1 (56x17x3 cm) inches, providing a decent amount of storage for books or decor. The installation was straightforward since the hardware for multiple wall types was included. They work well in the kitchen for spices or in the bedroom for personal belongings.
One tip for a secure fit: use a level during installation and make sure the bracket is flush against the wall before sliding the shelf on, or your photos might look like they are sliding off a mountain 📐
These shelves offer a clean, modern look and stay stable once mounted correctly. They are a practical choice for adding functional display space to any room 🖼️

Good looking shelves and easy install - skip the included drywall anchors
Color: Black, Number Of Shelves: 2, Size: 22in
I installed these shelves in a bedroom to get things off my dresser and some decor. Once mounted they look really nice. The black finish looks clean and modern and they blend in well with the room.
Installation was pretty straightforward. The metal bracket mounts to the wall first and then the shelf slides over the bracket. As long as you take your time lining things up it’s a simple project.
One thing I strongly recommend is not using the white plastic self-drilling drywall anchors that come with the kit. I’ve used that style before on other projects and they tend to strip out easily and leave larger holes in drywall. I used better anchors instead and the shelves mounted much more securely.
The rest of the hardware worked fine and once installed the shelves feel solid and hold items well.
Pros
- Clean modern look
- Easy installation
- Feels solid once mounted
- Good size for books or decor
Cons
- The small level included isn’t very accurate — use your own level
- One of the metal brackets was slightly bent out of the box but straightened out easily
Helpful tip:
Use your own level and better drywall anchors if you have them. It makes installation easier and the shelves will mount much more securely.
Final thoughts:
For the price these are nice looking floating shelves that install easily and work well for light storage and decor.
