This is a glossy printed metal sign that's safe for indoor or outdoor use. The rust on the edges is part of the printed design. Think of our signs as an art print done on metal instead of paper. They are lightweight, easy to hang and easy to store when not in use. (Please note: This is part of a series of girls I will be creating for all of the holidays and seasons. While I dont put my name on all of my designs my girls will have my Suzee signature. These are original artworks created by me and only available through our Ansel House shops) The glossy finish protects it from the elements if you want to use it outside or in a humid area like a bathroom. They are completely safe for indoor or outdoor use. We try to offer unique designs that you can use anywhere in the house or even outside without worry. Available in 2 sizes. The video is of the 9"x12". The 9x12 has 2 holes located on the top and bottom. The larger sign is 12"x18" and has 4 corner holes. Both are printed on rust free aluminum which is safe for indoor or outdoor use.
