GBS Potassium Alum Stone 80G All Natural - Soothing Aftershave Facial Toner to Close Pores Helps Sooth Nicks and Cuts

First of all is not a natural alum stone this one is a rebuilt from dust of alum. Is the cheaper and itchy version of alum, nothing to compare with osha stone. Secondo the plastic box come broken and the stone have a fracture line at the 2/3 of the lengt

This was smaller than I expected (think about the size of a hotel bar soap, but thicker).It seems to be decent quality -- it's non-porous and consistent in shape and texture.It also seemed to work well when I used it after shaving last night.

It soothes and takes away the sting of razor rash or cuts immediately. A must have to incorporate into your shaving routine.Wish it came in a deodorant style sleeve to apply. It works great but the sleeve would be better for application.

It's like a 1x1 inch block, a little smaller than a matchbox.From the amazon picture it seemed a little bigger.Works fine though as astringent

Does it's job well.
