Once the molds are prepped, they are good for many soap pours. All you need to do is align them, secure the two halves and pour. Each sheet mold produces one 3-D soap. You can purchase the molds at GoPlanetEarth.com. You'll find the Oval Leaf listed here and the Popsicle here. We're offering a limited 15% off introductory special on them right now; so, this would be a good time to make your purchase.
One tip when using these molds: Keep your pouring temp to around 135 to 139 degrees (Fahrenheit). A lower pouring temp will keep the soap from seeping out between the joined halves. I had no noticeable issues with soap seepage when pouring at a lower temp.
