***Both Indoor and Outdoor versions are made and are difficult to tell 1 from the other. Most volume is indoor use. Many sign companies use this material. When compared at the same size, with holes (only straight, no c/s) and the same size digits, these are often priced well above $12 each with the “Outdoor version”.
