Just heat in hot water for 3 minutes, press onto any object, and within minutes you have a high-resolution reusable mould. This 4-bar pack provides approximately 24g total material for multiple projects - perfect for duplicating miniature parts, creating conversion pieces, copying details and producing custom components without expensive silicone or complex chemistry.
🔥 Game-Changing Features
Never buy moulding material again - reheat and remould hundreds of times without degradation or loss of detail quality.
No mixing, no measuring, no curing time - simply immerse in hot water until soft, then create instant moulds.
Captures microscopic details, fine textures and intricate surface features - perfect for miniature weapons and delicate components.
Works with epoxy putty, polyester resin, acrylic resin, green stuff, milliput and most casting materials - nothing sticks permanently.

💡 Step-by-Step Usage Guide
🔹 Step 1 - Heat: Place bars in hot water (70-80°C) for approximately 3 minutes until completely soft and translucent
🔹 Step 2 - Shape: Remove from water, quickly dry, then press firmly onto object to capture all surface details
🔹 Step 3 - Cool: Hold in position for 2-3 minutes while material cools and hardens around the master
🔹 Step 4 - Cast: Fill mould with chosen material - epoxy putty, resin, green stuff or other casting medium
🔹 Step 5 - Demould: Wait for material to cure, then flex mould gently to release perfect duplicate

🎯 Perfect For These Hobbyists
✨ Key Advantages
⚠️ Important Notes
🔸 Temperature: Water must be hot (70-80°C) but not boiling - boiling water can damage material structure
🔸 Undercuts: Best for simple shapes - complex undercuts may require two-part mould techniques
🔸 Working Time: Material remains workable for 1-2 minutes after removal from water - work quickly
🔸 Lifespan: With proper use, bars can be reheated hundreds of times without performance loss
