Once a blank has been machined, there is no way to tell if there any problems with the blank or user error. Alumilite blanks, although not brittle, are still plastic and proper techniques must be used when working with them. As with any material, plastic/resin is susceptible to breakage under certain circumstances which are out of my control. Custom orders cannot be restocked, so certain exclusions apply. All I ask is that you contact me if any problems arise so that I can try to remedy the situation.
Often times, blowouts occur due to improper glue bonds between the tube and blank. Check out our video on how to reduce blowouts through proper preparation and glueing of tubes in pen blanks: https://youtu.be/JYM9WH4S8vY
