Merco M220 Flagging Tape is what's commonly known as Surveyors' Tape. Plastic ribbon so loud that the guy looking through the sighting thing (forget the name at the moment) can't miss it. Used extensively by surveyors, landscapers, forestry, outdoor safety people, miners, scouts and trail markers, construction crews and anyone who needs to mark, see and be seen. But there are a million uses. At this price, be creative!  Made of an extremely high quality polyethylene film. We stock 8 colors to suit most every industry: Surveyors, Forestry, Utilities, Growers & Agriculture, Miners, Woodsman and Hunters and more. Suitable to -10F.
