The heart of MAST is Mellow, Sofie, and Tasha. We are longtime friends, and partners of sixteen years plus, who create all of our jewelry and leather goods in our individual Tucson studios. We bring our personal collections together to make up the foundation of MAST.

We work cooperatively to further curate what we hope is an inspired and welcoming store with functional and mindfully made products. Offering form and function in both the everyday staple and the modern heirloom. This is the standard we set for ourselves as artists, as well as, for MAST as a whole.
