Question: How deep are the inside of the shelves, please?
Document: I had to use some fast drying wood glue to hopefully hold it together; and I have barely moved the shelving because it might fall apart.It's nice in that each shelf has 3 different levels to choose from.I wasn't interested in the doors, so they are put away unbuilt.The shelves are almost 7" deep (see how the edge of a paper isn't on the shelf).
Needed additional storage space in the master bath. Combined the wall with the matching floor cabinet and the set works beautifully. I am impressed with the quality of the product. Great value. The dimensions of the wall cabinet are 21" Wide x 24" Tall x 8" Deep. The dimensions of the matching floor cabinet are 26" Wide x 35" Tall x 12" Deep.
After looking at all of the white shelves and cubes and such, I decided on this wood-like one to fit my spot. It's made out of MDF, an acronym for Medium Density Fiberboard. All parts were there, easily seen in it's packaging. The directions are just drawings.The most difficult part was putting the top on with the round swivel gadgets. I don't think they fit at all, and the dowels that go into the top to the side shelves seem useless...
For years I had been looking for a small wooden cabinet with glass doors for my kitchen to hold spices and teas but to no avail. I was even considering having one custom-made when I came across this cabinet at Amazon. Perfect. Perfect for me. The size, the glass doors, the two adjustable shelves, the wooden finish with pewter-like hardware -- all of it fit my criteria exactly. Oh, and at a very reasonable price, too!
I love this cabinet. I wanted a cabinet on the wall so I didn't have to worry about anything on the floor when mopping and love this. I actually put the window privacy or frosted window stuff on the glass - so not all could see what is inside and is perfect.
I have little space in my kitchen and have been searching for a breadbox that hangs on the wall. This cabinet wasn't designed to be a bread box, but I couldn't ask for a better one. I placed  narrow decorative baskets on the shelves. After I bake two or three artisan breads, I put the bread in clear plastic and place them in the baskets.The clear glass doors display the baskets and the artisan bread, it makes a perfect bread cabinet. I highly recommend the cabinet.
got what I payed for looks good a little hard to put together but it serves the purposenot high quality materials
Why on Earth would you want something like that in your life? Your kids sleeping in it? Your family hanging out by it? Your air filled with it? It's asinine. Do a quick Google search on the topic to learn more. It's scary. "I notice all the other glowing reviews said how easy it was to built, somewhat suspicious, to me.
We got two for our wall as well as one floor unit for our 'bar'. It looks great. They show off our glassware beautifully. Nice stain color and nicely made. Took very little time to put together.
Very easy to assemble and it looks just like the picture. It's a nice way to add storage to a small bathroom.
Answer: The shelves are 6 1/2 inches deep
