It’s a righties world, and we’re all living in it. Roughly 90% of people living in Western countries are right-hand dominant. Lefties know the everyday struggles that come with being born into a world that designs almost everything for right-handed people.

To help try and make things a little more right for lefties, August 13 has been named National Left Handers Day . On this day, we’re asked to think about all the things righties might take for granted — like grabbing a measuring cup or strumming a guitar. “August 13th is a chance to tell your family and friends how proud you are of being left-handed, and also raise awareness of the everyday issues that lefties face as we live in a world designed for right-handers,” a message on the National Left Handers Day site reads.

For lefties, the start of the school year is one time that could require a learning curve. Many school supplies are made specially for righties — from spiral notebooks to pens , scissors , rulers , and more. Due to the lack of adequate support, lefties might struggle with right-to-left writing systems, suffer from hand cramps, or require additional time to complete the same tasks as their fellow students.

But, that doesn’t mean 10% of the class should be left in the dust. In honor of lefties, we’ve rounded up a list of all the handy back-to-school essentials built just for you! I May Be Left Handed But I Am Always Right Mug You can give your favorite lefty a cup of coffee and a little laugh .
