Prehaps the best, purest alum block available.
This world class Shavex alum bar is top quality Potassium Alum: clear and translucent. And it comes in a very handy plastic container.
Use prior to applying your aftershave to close pores, repair small skin abrasions caused by the razor and as a very effective bactericide that promotes healing.
Leave on face about a minute then rinse off with cold water & proceed to applying your favorite after-shave.
Generous 110 gram bar.
