Most bands don’t have particular meanings. Individual purchasers may give different meanings to their own band based on something in their life of their interests. A few designs such the swirly hand design is a symbol of service, a “helping hand”.
The hope is that the bracelet itself becomes a symbol. A symbol that you supported a project and students in need. When you wear a band you become part of the Yuda Bands Revolution and hopefully have a greater resolve to help others.
