    Just okay
    Color: Grey Striped, Size: 72"W x 84"L (Pack of 1)
    Okay curtain, not great, but not bad. Looks like it has kind of a faint background design. Has a plastic type feel. Looks okay.

    Pleasantly Surprised!
    Color: Grey Striped, Size: 72"W x 72"L (Pack of 1)
    I was looking for this exact product but didn’t know it! We recently moved into a new home and had zero window treatments so needless to say I wanted something quick, affordable and not vinyl WalMart blinds. We are happy with our purchase and would highly recommend to others. Some complain of the adhesive not sticking- make sure to clean the window wells/walls etc prior to installing these. If the surface is free of dirt/grease there will be no issues with them staying put.
