These have to be some of the tiniest accessory parts ever! You'll definitely need your tweezers and a good magnifying glass to position these microscopic 7.92mm Mauser casings (no bullets; just the empty casings) on your model or in your diorama. Look closely (magnification required) and you'll see that they're actually quite detailed, including the base rim, strike plate detail, and bullet end taper. And believe it or not, the ends are actually open! Absolutely amazing!
