Review on Magic Shell Grinding Dressing 150X25X25Mm by Jay Matlock

I have two old table coffee grinders that belonged to my father. He gave them to me and I've used them for years on all kinds of small projects. I was just "curious" about how to "bring the flatness back" to my grinding wheels and realized you need "Toilet Stone". Well I bought two of these (one for each grinder) and they work GREAT! You'll learn something new every day and your Magic and Shell toilet block will fix years of "neglect" in just minutes. Works perfectly! Thanks again! Ed
