The plugs appear unused, but they have been stored for several years. Although the part number is the same, there are two different types of boxes (see image 1). Although the part number is the same, the plug design differs in sets of 3 (see image 3). One plug has a slight stain (see image 6). Due to the damage to the outer box, storage period, stains, and different box types, this is a bargain listing including shipping.
