What to consider before buying

Consider the type of mold you need: alginate for lifecasting, silicone for reusable flexible molds, and resin or plaster for casting. Pros often choose platinum-cure silicone for durability, while beginners may prefer tin-cure or latex. Always work in a well-ventilated area and follow manufacturer instructions.
