I had purchased extra 7.5 pound silicone liners in the past and finally decided to make the big purchase for this bad boy...It has by far exceeded my expectations! I have consistently used the 7.5 pound premium molds from Nurture and absolutely love them, but as production is getting bigger, I wanted bigger molds. I finally decided on this mold and it is perfect. Be aware, it is going to be heavy, but by far so much more convenient to have such a huge wooden mold to pour large quantities of soap. I put a large lid over the entire mold to insulate and my soap comes out like a dream! I also love that the sides and middle wooden slates come out just like their premium molds. As always, high quality construction! Saving up to get another!!
