BATMAN 89 BATMAN GAS CAPSULES REPLICA

From Paragon Collectibles. Used primarily to mask his escape, these diversionary devices are among the numerous gadgets carried by Batman. Paragon FX Group has replicated these fan favorites in steel and glass and packaged them as a set of 3. Each set ships in a themed tactical case, complete with custom foam cutouts. These capsules will ship empty but can be unscrewed to add the color of your choice. (Shown with water and blue food coloring)

NOTE: No, they won't do anything if you throw them on the ground. Well, except break.
So, don't do that. Intended for display only.
