Is there some place in the world (or in some parallel universe) where Smarties are rectangular? I never knew. And thus assumed that Pez were unique in the candysphere.
The “in the U.S.” distinction for Smarties is because, in this country, Smarties is the name of a chalky candy, similar in texture (but not shape) to Pez. In most of the rest of the world, Smarties is the name of a candy-covered chocolate candy, very similar to M&Ms. Those Smarties aren’t distributed in the U.S., because of M&Ms’ presence.
