- The ultimate tanning essential for a streak-free finish and stain-free hands. This mitt evenly distributes all St.Tropez tanning formulas onto the skin, whilst the water-resistant barrier ensures hands remain unstained, for flawless results with every application. Remove the mitt from the plastic outer wrap, put onto your hand and then add your chosen tanning product onto the application side. Then, with long sweeping motions, work the product into your skin. To clean, soak in soapy water, rinse and let dry.
