Link to Soap

Ok so I was out and about and I ran across this product. Link provided to the product. Disregard the price. Got it from NEX on base. I was wondering if anyone used it. I picked up a puck thinking it was just a puck of shaving soap but when I got back home I saw it was a dual soap. So the big question is are both sides usable as shave soap? If anyone knows that would be great. If not we will soon know as I will try both sides some time in the future.
