SW Complete Decal Set
Includes two stickers for all members of the 501st Strike Witches, with pan and nopan versions. Eila comes with an additional third alternate pan design. Set also includes two extra stickers for Kunika, the best girl of the 506th.
These are vinyl decals, and are suitable for outdoor use. This includes on cars, range cases, or whatever else you can imagine.
I can't recall the exact dimensions since they vary slightly per design, but I believe they're all 4 inches tall.
Normal price on stickers is $6.50 a pop, and this set would normally run at around $175. When buying the bundle, the price per sticker comes out to $3.70.
