Live Life Hands-Free
We created the Big O Key Ring in 2012 to give women of every age an extra hand to hold onto what's important.
Whether you’re a mom, a student, or a boss babe with a million things on her plate, you can rely on the Big O Key Ring to be your well-rounded life hub.
Secure Locking Clasp
Every Big O Key Ring is outfitted with our strength-tested, patented, locking clasp. We designed it so that we could swap our keys in and out securely, and without breaking a nail. Gone are the days of fumbling with the key swap at the valet - with this locking clasp, you can rearrange with a click.
The rigid interior core of our bangle keyring helps the Big O to maintain its shape and long-lasting durability. The non-bending, anti-squish design means it can withstand everything you can.
We're the O-riginal
From the locking clasp to the premium materials, these are the 6 reasons why #Ogirls of all ages choose to invest in an Original Big O Key Ring instead of a knockoff.
A Big O for Every O-ccasion
Easily washable, velvety soft, and totally life-proof, the Silicone Big O Key Ring is a go-to fan favorite.
Luxe, Genuine Leather
Crafted from genuine, coated leather, the Leather Big O Key Ring is a super durable, fashionista favorite.
Inspired by our favorite stackable bangles, the Resin Big O is a lightweight, swirly statement-maker.
