Grafix Ink Jet Film, 8-1/2-Inch by 11-Inch, 6-Pack, Clear

Can this sticker removable? reusable?

Can I "reverse print" on these sheets so that I can place them inside an office window, readable from outside the office window?

Would it be possible to print white lettering to this and then apply it to a black surface?

Can I use these with Colors laser printer? I need to print in colors not only B&W. Thank you :)
