I am a soap maker so I'm always on the look out for new molds. I love and prefer silicone molds over a very plastic or acrylic molds because it is just much easier to take out. Although not as ideal for cold process soap making, I prefer this for M&P soaps. Each cavity holds about 2.4 - 3 oz. After cooling, it is very easy to just pop right out of the mold. Bath bombs or bath tablets can be made in this too.
