⚠️Important Information about Lifespan
Note: Silicone molds have a finite lifespan when used with aggressive polyurethane resins. The chemical properties of certain resins can degrade silicone over time, potentially resulting in reduced detail and shorter mold life. For optimal results, we recommend regularly checking the condition of your molds and replacing them in a timely manner.
