This is a lock guard for a CARL heavy-duty punch. Two have been used, leaving 8 remaining. It is unclear whether the marks in the center of each guard are from use or were present originally (they are not rough to the touch). Please be aware of this. This is a used item that has been stored for a long time, so the outer bag is somewhat worn. Please understand this. - Brand: CARL - Model: K-10 - Quantity: 8 sheets - Application: Lot Guard Thank you for viewing.
