    Product description

    The slab liner will hold approximately 60.8 ounces (3.8 pounds) of oils and will make approximately 4 pounds of soap. The soaps made in the slab liner can be cut to any width or length you prefer and many different sizes are possible. It's all up to you! The end pieces of the wood mold are removable so you can easily remove the liner.

    Love it...but a lil too short?

    I love how well made this mold is, including liner....I just wish the height was littler higher...My suggestion is to move the .25 off off the length of 9.25 to the 2.63 height the final would be 9 "L x 6.25" W x 3" H... to me it would be perfect size...

    The 4 pound slab

    My favorite mold

    This is a great mold. Well made, strong silicone that doesn't bend in. I get 18 bars so it's perfect for soaps that are popular sellers. Just bought a second one!

    Wish it was deeper

    It’s not as deep as I would like it. When I cut it into loaves, it’s a bit smaller than my single loaf bars. I did notice that it needs a little over 80oz of soap to fill the mold completely. I can 18 bars and some samples

    ❤️ this mold

    Sturdy mold with thick silicone liner. I bought this specifically for sample bars as I have a couple of your five lb molds. This will be a repurchase for me. Arrived today and I just couldn’t help myself.

    I've everything I always order from you. I haven't used my 4lb slab mold but loved. Can't wait to try it . Thank you so much

    4 lb Slab Mold

    This mold is perfect for me. I have only been soaping for 1 year and wasn't brave enough or confident enough to go for a really large mold that uses a lot of oils ($$$$$). I love using this mold. I use this mold the most. Design possibilities are endless with a slab mold. You can cut the bars any way you want and to any size you want. With no waste at all I am able to get 18 bars, 2.125" x 3.00 x 1.2"

    Perfect 4# mold

    I splurged and bought this box and liner and absolutely love it. It is super easy to remove the liner and unmold soap. I used it for a bulk order of baby shower soaps.

    Smaller than Expected

    This mold was smaller than expected. That is my mistake and next time I will buy a larger one.
