The positive message of "Run Fast" is sure to get notice with the easy to read Julius-K9 labels, allowing you to easily customize your K9's harness. The "Run Fast" message is reflective, and the Julius K9 web address is phosphorescent. Therefore the patch will glow under any circumstances, even in complete darkness. Features a velcro back for affixing to your harness or other gear, and patches are easily interchangeable if you desire to use a different message. Each package contains two patches, one for each side of the K9 harness. The Small size measures 4.3" x 1.7" and the Large size measures 6.3" x 2".
