Mark-A-Cow Legbands feature a push-button release mechanism so they are as easy to remove as they are to put on. Made of tough DuPont nylon, Mark-A-Cow is 1.25" wide and 13" long so that the protruding end acts like a flag to alert the dairy farmers to marked cows. Several colors are available making these legbands perfect for use in a color-coding system, such as RED for antibiotic, PNK for high-SCC etc. Use of markers is not recommended.
