They really are tiny. Completed models are between 1 and 2 inches tall. the Tinysaurs fit inside a 54mm diameter dome (that's 2 1/8 inches in imperial units).
We ate at a cafe in the Bronx a few days ago called Tiny's. The owner responded to his nickname while we were there. He was taller than 6 feet and heavier than 200 lbs, so we get it. Everyone uses tiny to describe something different -- sometimes ironically.
