Question: Is the shelf clear or frosted glass? What is "brass glass'? Thanks
Document: This shelf was easy to install, looks fantastic, and provides a great space in my bathroom for my shaving stuff. The shelf is thick frosted glass, the mounting hardware was easy to install, the finish blends in exceptionally well with my other items. All around satisfied.
I ordered three of these frosted glass shelves for the corner of my Vigo Frosted Glass Shower, and the minimalist design of the shelves matches perfectly the general &#34;clean&#34; design of the two glass walls and door of the Vigo shower.
The shelf support system is poorly designed with only two points of support, it needs a third support in the corner to keep shelf from tipping.
First, there were no installation instructions included. I didn't have a problem with that, but some may. The plastic wall anchors included were cheesy, so the initial installation (in a porcelain tile shower) left the shelf loose & wobbly. After reinstalling with proper anchors, the shelf is tight.
:-) FYI standard #6 pan head screws will seat perfectly in the mounts....no need for flat head. Once I got these screws it went up great, using a 3/8&#34; concrete bit with water poured while drilling on masking tape. Looks great and works much better than any of the suction crap we tried from BB&B (and cost about the same as the fancy shelf we replaced!)
much better in peson, not flimsy at all. looks great. why i  need 10 more words is beyond me, oh well.
This is a high-quality item that is exactly as it appears in the ad. We r very pleased with this item.
Just what we needed to hold my husbands shaver and accessories. More room on it than I thought there would be..
I used this in my shower. It holds an orchid plant, flameless candle my shampoo/conditioner and a few other bits. It's useful and elegant.
Finally got these up. Didn't like the tiny anchors they came with, which is why I deducted one star. I ended up using toggle anchors, but the only ones the hardware store sells are not stainless. I used the standard hardware store anchors but elected to order stainless screws from McMaster-Carr.
Answer: no
