About 10% of the population is left-handed. And 100 per cent of left-handed people do not correctly read the promotional message printed on products, such as mugs and pens, which fulfil their function once gripped. Then there are items, also used as gadgets or gifts, that left-handed people find difficult to use: scissors, the roll-up tape measure, analogue watches with the winding crown located towards the arm and not towards the hand (if you wear it, as left-handed people usually do, on your right wrist), pencil sharpeners, to name a few examples.

While it can be argued that lefties represent a small minority, why cut them off from communication?

A pen or mug can be branded on both sides; thus, no matter which hand you hold it with, the logo remains legible. If you don't intend to invest in this, you can opt for gadgets that can be used by right- and left-handed people: t-shirts, bottle openers, notepads, bags, and water bottles.
