As far as shaving soaps go, I find this Crabtree & Evelyn Sienna Soap to be the best. Once I tried it, I never changed neither brand nor scent. Using a Silvertip Badger Brush, this soap produces a thick lather that will both protect and discretely scent your skin with a Renaissance floral essence that will not clash with most after-shave lotions.
The wooden bowl is well built, sturdy and heavy enough for the shaving brush not to cause any wobbling; what is more, you only need to buy it once - original Sienna Refill Soap is available at half the price.
If you already have your own shaving soap bowl, keep in mind that the contained 100g soap is 8.5cm (3.3") in diameter. Of course you can always microwave it to fit ;-)
