This kit includes the wearable rubber parts to rebuild your letter opener.
Note: This is only for the newer current style machines! If your machine is 20 or more years old these parts won’t work.
The easiest way to tell the newest style is the conveyor pulleys are black plastic instead of silver steel. Most older style machines are below serial number 25000.
