Made of durable 1 sided .045" thick white glossy coated outdoor aluminum that is UV resistant.  These extrerior grade aluminum stakes are UV-resistant, easy to clean and have a consistent, high-gloss finish. Mfg expected life is up to 3 years for sign-based art and up to 2 years for photography-based art. But from our own personal use and testing we can tell it will probably be longer depending upon the amount of UV rays that hit it and your geographical area. We have had some out year long for over 4 years and still look great. These are a beautiful way to display messages for gifts, garden plant markers, point of purchase display signs and small memorial signs.
 
Size is 4" x 7" From the top of the stake to the bottom.  Main imprint area is 4" x 2.75".  Stake is .75" x 4.25"
These can also be slightly bent if you prefer after you recieve them as they are made of aluminum.
