As you can see there are several different types of shell you can get depending on your application. The flex pearl from mud hole is good if you are wrapping cylinders. No I dont use this in my blanks. It is a new product that has been on the market less than a year. The stuff from stewmac and duke of pearl is a lot thicker. Thin lam is .012 and reg pearl is.040. All of it is true abalone it just the different process cutting the shell.
