This product is suitable for indoor use, it is advisable to use and placed in the plane.
As other reviewers have noted, it's pretty small (the product descriptions are accurate - I suggest getting a ruler to visualize how much space this will take up before purchasing), but all the features work great.
I bought this to use on my desk at work and I was pleasantly surprised as to how much I like it and use it.
I use the slots for post it notes and other small papers.
I like a clean desk and this is the perfect organizer because it doesn’t take up a lot of space.
Cheap material, easily bendable, package came damaged.
Smaller than I expected.
But it works.
Read the specs, much smaller than you think.
I expected it to be bigger but it was small.
