Tribble Razor
The fine print of a commercial referencing a tribble razor
The Edward Brand Tribble Razor was a type of razor that was specifically designed to shave tribbles.
According to the fine print in a commercial for Tribbles cereal, it was recommended that each tribble should be shaved with a tribble razor before consumption, as the fur was considered a choking hazard.
Tribble razors were included with the Tribble Cereal Super Salon playset, which was sold separately from the cereal. (ST: "The Trouble with Edward")
