Where can I buy one of those little handheld vacuums EXACTLY or ALMOST EXACTLY like the ones shown in Gattaca?

The little handheld ones for your keyboard! I've seen a lot of them, but I want one that resembles or is the exact copy of the one shown in the movie Gattaca, the one Ethan Hawke/Vincent Freeman uses all the time to clean his keyboard to avoid leaving behind fragments.
