How To Use
  • Beginner-friendly
  • Reusable mold
  • Easy release
  1. Prep

    Mix your bath bomb batter until it holds its shape when squeezed.

  2. Fill

    Pack the mold firmly, slightly overfilling so every detail forms.

  3. Press

    Press down evenly to lock in the shape and sharp details.

  4. Release & dry

    Unmold gently and let dry for 24 hours before handling or packaging.

Pro tip: Batter too dry cracks, too wet spreads. Aim for damp sand that holds when squeezed.
