1 deck each for each ship in the clas: Akizuki; Teruzuki; Suzutzuki; and Fuyuzuki.  The decals are thermally printed on clear waterslide decal transfer paper. The grey background is for visual effect only. The decals are made up of just white lines on a clear background so the painted deck color will show through.  You will want to cut out as close to the white lines to ensure a good proper fit.
