Thin, durable, good plug orientation
Size: 6.5 Ft, Color: Black
This has been great for behind our entertainment center. We have a lot to plug in between floor lamps, tv displays, PlayStations, and pcs. No problems so far and much better than chaining extension cords. Would buy again

It holds so many plugs!
Size: 6.5 Ft, Color: Black
I am using this to plug all of my Christmas village pieces in. I haven't used it yet, but it's going to be great to keep the plugs all in one area.
