What makes these products left-handed?

Scissors are true left-handed shears with the blades reversed, and the grip designed for left-handed use. Very comfortable to use due to the soft grip. Lefties can see what they are cutting with these, and cutting is much more precise.

The ruler reads from right to left, the reverse of the standard right handed ruler.

The Viseo Pens are shaped ergonomically for left-handed comfort.

The mug only works when held in the left hand. The graphics face the mug holder, and, more importantly, nothing will spill. When held in the right hand, liquid leaks out of a hard-to-see hole, dripping onto the foolish right handed drinker's clothes.
