This smooth, slow-drying modeling clay is perfect for detailed sculpting and design work.
(€ 24.56 without 21% VAT)
This clay is formulated to be very smooth and slow-drying, making it ideal for projects that need extended working time and fine surface refinement. Its soft, pliable texture allows for exceptional control in sculpting, carving, and shaping, suitable for detailed maquettes, product design prototypes, scale models, and character sculpting.
This clay is a reliable material for professionals needing accuracy, smooth finishes, and a long working window when creating prototypes or artistic models.
Condition the clay by kneading until soft and workable. Sculpt, carve, or shape using hands or modeling tools on a clean surface or armature. Keep tools slightly damp or smooth surfaces as needed for fine detailing. Because of its slow-drying formula, unfinished work can be refined over multiple sessions. Store wrapped or sealed when not in use to maintain workability. This clay is intended for modeling and mold-making only and should not be kiln fired. Clean tools and surfaces after use.
