Colors include , purple, red, green, blue, black, and tri-color Ribbons are made of either silk or cotton. Cotton ribbons last the longest, and are less expensive than silk, but silk ribbons give a visibly cleaner and more crisp impression, which is desirable when using to document very important information such as transcripts, certificates, or legal documents of any kind. Our purple ribbons last the longest and give the most security out of all our solid colors, and the tri-colored (purple/green/red) ribbon supplies the highest level of security out of any color ribbon we carry. we also supply this ribbon in a dual color (black and red) as well.
