I suspect that’s older than the one I’m using but probably as good or better. The CUP soap predated the MUG soap, I have heard the CUP is better/best but I’ve not tried the mug version. I like it. Give it a short soak and it’s good to go.
Chris is right. The cup is an older formula which is much better than the mug soap. Nice score. I'm suffering from vintage soap envy.
I’ve got an extensive collection of vintage soaps, including wrisley and yardley. I enjoy restoring the old wood bowls. One of my prized possessions is a NOS Williams wood bowl with untouched soap. I have two bowls with Williams but only one is new. I’m amazed at how well the vintage stuff lathers.
Of course none of the vintage soaps are scented with anything other than old age and mold spores...I LOVE the smell of an old soap.
