Size: 4" x 4"
Material Type: Fluorescent Yellow Green Diamond Grade Reflective Aluminum Sign
Fluorescent High Intensity Reflective Delineator
These are very high quality reflective markers. The diamond grade reflective sheeting is very visible and reflects approximately 60% of the light that hits it. I'm using these in conjunction with another reflective marker and together they provide a highly visible array that is easily spotted at long distances.
