This wonderful coffee mug is part of the Fearless collection of products from Natural Life. This collection of products is a collaboration between Natural Life and an organization called OCD Jax, which offers support and raises awareness of the problems of anxiety disorders, in order to empower and reduce the stigma. In fact, a portion of the proceeds from these products goes back to OCD Jax to help them in their mission. This mug is made of ceramic, even though it is designed to look like an enamel camp mug. The words say A WORRIED MOTHER DOES BETTER RESEARCH THAN THE FBI, and the colorful flower wreath is a nice touch. This mug is double sided and safe for use in the dishwasher and microwave. When heated, it will become hot, so be careful! Made by Natural Life, this mug holds 16 ounces and measures 4 inches tall by 3.75 inches wide.
