These low-cost diamond-shaped signs can mark a trail or help users differentiate between a hiking trail and a portage where they meet or cross. Simply place them at a visible distance one from the other to inspire confidence. Standard hiker symbol. Tough blue UV plastic and white UV ink means this image will last outdoors. Each has 4 holes for mounting and measures about 12x16cm (~4.75x6.5inches). Popular with parks, trail & canoe route managers, this also makes a nice gift for the avid hiker.
