Lynn Peavey HotShot Fingerprint Developer, 72 Pack

With our tried and true HotShots, you won't have to worry about poorly developed, transient and faint latent prints, wasted chemicals, mess or guesswork. This self-contained and disposable product can finally put your mind at ease. Within a few seconds, the activator solution is absorbed and a chemical reaction takes place, generating heat and a controlled amount of steam for needed humidity. As the canister heats, the HotShot fingerprint developer begins to vaporize and fills the fuming chamber with extremely sensitive, active print-developing fumes. HotShot is all inclusive to fume several items in a contained chamber. After use, simply screw the lid back on the protective container and throw the unit away.
