  3. Apply Etching Cream: Cover the exposed areas with an etching cream, following the manufacturer's instructions.
  4. Wait and Rinse: Allow the cream to sit for the recommended time before rinsing it off under cold water.
  5. Remove the Stencil: Peel off the stencil and clean the tumbler again.

This process creates a permanent, stylish design on your tumbler.
