Treat yourself or someone you love with this gift of comforting warmth. Simply heat these wrist warmers up in the microwave then, slip them on and feel tension slip away. Hot therapy helps provide temporary relief from muscle and joint pain. A blend of twelve herbs smells incredible, but is also designed to relieve tension, promote sleep, reduce anxiety, clear the mind, and deepen relaxation. Can also be chilled in the freezer to help with sprains and strains. One size fits most.
