In brass, the medallion measures 32 mm. The inscription in raised relief on the reverse reads "For Loyal Service." The issue box is in light cardboard, laminated with leatherette-textured blue paper. Inside, the fitted space for the medal is lines with ersatz short-nap velvet, the lid is lined with light foam rubber.

The medal is in very fine to excellent condition: just very slight pitting to the obverse. The ribbon bar perfectly clean, the brass sticker with the anchor is in place and wear-free. The issue box shows moderate wear to the blue laminate paper and corner separations on the left side. The fabric hinge is a little loose due to a tear to the laminate paper covering it.
