The floating shelves are great
Size: 24"W, 2P, Color: White
I finally found a complete set of Japanese tea cups. I had bought 2 in Canada at Sypson and Sears. I had went to visit my family in British Columbia. But I couldn't find the rest of the set. I finally found the rest. My son-in-law installed the four shelves. They look nice and work great.

They're ok.
Size: 36"W, 2P, Color: White
The shelves are good but the wall brackets need more varied hole spacing, and the holes on the shelves for the bracket arms are loose so even screwed in they move a little bit.

Solid, easy to install floating shelves
Size: 20"W, 2P, Color: White
I really like the ease of installation of this set of floating shelves. The only requirement is that the bracket is mounted on the studs not just to drywall, or that appropriate drywall anchors are used. Once the brackets are secure, the shelves go in like a sleeve and you have yourself an awesome floating shelf. Good quality materials and fair value for the money. Great find for DIY.
