Big O® Key Ring Comparison: Resin, Silicone & Leather Differences

Big O® Key Ring Comparison: Resin, Silicone & Leather Differences

The Original Big O® Key Ring isn’t just any keychain—it’s a hands-free essential that makes your busy life easier. Whether you’re juggling errands, chasing after little ones, or heading to brunch with friends, the Big O® keeps your essentials within reach without the hassle of digging through your bag.

But with three signature materials—leather, resin, and silicone—how do you know which one is right for you? Don’t worry, we’ve got you covered!  Each material is designed for functionality, durability, and style, but they offer different benefits when it comes to fit, weight, feel, and care.

Big O® Key Ring FIT

Let’s start with diameter. Resin and Leather Big O Key Rings both have a 4-inch diameter, while Silicone has a 3.75-inch diameter. The slightly wider diameter means that Resin and Leather are perfect for those who have larger wrists and hands, or those who like to wear their Big O Key Ring above their elbow.

Big O® Key Ring WEIGHT

There is a slight, yet noticeable difference in the weight of the three types of Big O Key Rings. Resin is the lightest weight Big O Key Ring. Both Leather and Silicone Big Os have reinforced inner cores to help them maintain their strength and durability. Of the three, Silicone is the heaviest Big O.

Big O® Key Ring SILHOUETTE

Now let’s talk about silhouette! Resin has a super slim, delicate-looking silhouette. Silicone has a slightly thicker profile than Resin, but is still on the thinner side. Leather is definitely the widest from a side view, which mainly is due to the way the seam is sewn. The silhouette doesn’t effect the function or durability of the Big O Key Ring, it all comes down to personal preference and the kind of look you want.

Big O® Key Ring CARE

The Original Big O ® Key Ring is all about quality and durability, so no matter which one you pick, it’s designed to withstand whatever your day brings. That being said, there are differences in the way you should care for your Big O Key Ring to maximize its lifespan. Resin and silicone are water-resistant and therefore can be washed with a mild soap and water. Our leather Big Os are coated, so they are also also highly durable, but since they are made from genuine leather, they cannot be submerged in water and should be wiped down with a damp cloth to be cleaned.
