Our mini massage bar soap mold is made from food grade plastic and can be used with melt & pour soap bases as well as cold process soap. This mold makes 4 bars, with each cavity holding 2.5 ounces (weighted). We recommend allowing your soap to cool for 24 hours for easier removal from the mold. If the bar won't release, place the mold in your freezer for 30-40 minutes and try again. We also recommend pouring your soap base at a maximum of 145°F. It's best to hand wash the mold with warm soapy water. Cleaning in the dishwasher or with hot water can warp the mold. Finished Soap Dimensions: 3" x 2" x 1 2/5" deep Made in the USA.
