A Unique Jewelry Stand
Color: B-Metal Antique Greenish, Color: B-Metal Antique Greenish
When I received the item, it was in bubble wrap and taped. It's like a spider's nest, so the item is safe during delivery. It is attached to the tree by a screw. The golden appearance and the patterns cut within the work look good. My only dislike about the item is that it accidentally poked my sister's thumb because some of the ends of the tree branches are not smooth out. Stability is good. However, I do think the screw loosens over time. It's heavy enough to keep itself in place. For what you're getting, it is decent for the price.

Great organizer for "normal length" chains
Color: B-Metal Black
This little tree has saved all my random jewelry from its fate of being a tangled mess in a zipper bag, or in my nightstand drawer, or the bottom of my purse...you get it.
If you have a lot of long (greater than 26 inches or so) chains, you may wish to opt for something taller. But for my purposes, it's just grand. Even nicer-looking than the picture also.

Excellent Buy, Quality Build, Great Price
Color: B-Metal Antique Greenish
Solid metal. Tree attaches to the base with a Phillips screw (four way). Sturdy attachment. Metal was intact upon delivery and me foolishly dropping it on the ground as I opened it out of the box. The tree is... how must I put it? Two dimensional I suppose, which you can see from the pictures the branches extend in only opposite directions. So it is not three dimensional in the aspect that the branches go every which way like an actual tree. This is what I had envisioned and I don't want you to make the same mistake. This product is what it says, my imagination ran away from me with the picture and I bought it very quickly. All in all a wonderful piece for the money.

Cute but sharp edges!
Color: B-Metal Antique Greenish, Color: B-Metal Antique Greenish
Its cute but has tiny sharp edges i cut myself when putting it together. I will buff it down and keep it. But the quality control is definitely lacking.
