It's a simple metal skeleton which your photographs are pinned to with really cool little magnets from the future. Because it holds your photos off the wall it makes them look like they're floating! Phlib come as standard with sticky 3M Command Picture Hanging thingies to liberate your photos in minutes, without having to drill holes in your wall and without the fear of damage or leaving tacky gunk behind!
Basically, it's the pain-free, friendly way of displaying your photos without torturing them (and yourself) with frames, clips, glass or backing panes.
And why is it called a Phlib? It's short hand for Photo Liberation!
