Service Dogs work at night, too!
As with most of our patches, we designed this patch when one of our customers asked it it was possible to create a patch that glows in the dark -- YES! It is possible!
Suitable for day or night, the thread that is white in the daytime glows green in the dark. The longer you submit it to bright light, the longer it will "hold a charge". Available in 2 sizes: 2" x 3" or 3" x 6". (Please note, the small size of this patch does not have the outline on the text.)
