Most of Laser-CutZ soap stamps are done in acrylic which is reasonably durable material and not easy to brake, but if you want extra durability you can upgrade to metal stamp which will make it next to impossible to brake the stamp plate. Even thin fine line of the stamp will stay there forever. Metal soap stamp are good for heavy duty production environments especially when press machine is used. In addition if metal plate is mounted on heated bed the you can stamp old and hard soap and wax candle.  Metal soap and candle stamp is good upgrade for your business branding and efficiency.
