Works great. Definitely holds 4 lbs of soap. (Not soap weight). 18 1 inch bars.

This slab liner is so thick! Well worth the price. This will surely last a very long time. Extremely pleased.

Perfect size for small batches

I haven't used this mold yet, but I can tell it is going to be a good size to start increasing my soap making. I've been using a 2lb mold and I'm ready to make 4lbs in this slab mold. It seems stiff enough that it doesn't need the wood frame but I probably won't fill it to the very top or if I do I'll support the sides.

I am just starting up my soapmaking business so I wanted to get a few different sized molds. I am so happy that I went with this one. Very nicely made and the soap slab just slides out like butter.
