Sleek and attractive

While these didn't come in the color I was looking for, the size and price point were just what I was looking for. Installing them didn't take too long and was simple enough, but the end result did seem a little more wobbly than expected. I used them to display mine and my boyfriend's boots, and they held up fine, but I think 22 lbs per shelf would be pushing it.
I was able to easily cover the shelves with wood grain look contact paper and easily trim the excess off with an Exacto knife to get the look I wanted. I'm happy with how it turned out.

Sleek Design That Hides Cables Well
Color: White, Size: 3FT(13A), Color: White, Size: 3FT(13A)
This flat plug extension was super easy to set up and works exactly as expected. We mounted it on drywall using anchors (not included), but that wasn’t an issue since we already had some. The flat plug design is great for tight spaces, and it really helped clean up our bedside area by keeping cables neatly hidden and organized. Definitely a practical and space saving solution!
