Using this UDOCOOL silicone mold is a breeze. First, prepare your chosen material like melted wax for candles, soap base, resin, or plaster. Pour it gently into the mold, making sure to fill it evenly. You can add some colorants or glitter to make your creations more unique. Once poured, let it sit until it hardens. For candles, you can insert a wick before the wax fully solidifies. When your creation is ready, carefully remove it from the mold. To keep the mold in good condition, wash it with mild soap and warm water after each use. Avoid using sharp objects that could scratch the mold. Store it in a cool, dry place to prevent any damage. With this mold, you can make beautiful rainbow - arch items for your home decor again and again.
