Artemis 65? Lotus 120? Apex 142? Huh?
When it's time to size up for a new toy, sometimes it takes more effort than it should. It's very common to see toys being sold as "Small", "Medium", "Large" etc. Every toy maker has their own sizes, so who knows if the "Large" you're about to buy is a reasonable (or ridiculous), step up from the "Medium" you have.
The thing is, a Grip 115 could be considered a "Small" toy to someone who can already take a Cetos 150... but that's an "Extra Extra Extra Large" to someone who's never taken a toy before! That isn't very helpful, as terms like "Small", "Medium", "Large" etc are relative to your current stretchiness. Having to hunt around for dimensions buried in clunky menus or walls of text can lead to mistakes when purchasing a toy, leaving you feeling cheated if it ends up being too small or even discouraged if it's too small or large to enjoy.
We wanted to make our sizing-convention as clear as possible and avoid attaching any form of judgment to it, so we named our toys after something objective and simple: their approximate maximum circumference measured in inches, multiplied by 10 to give it a nice round number. So when you see the Gape Keeper 93, you'll know it has a 9.3" circumference. Likewise with the Mordax 115: 11.5" circumference. The Chute 75: 7.5" circumference, so on and so on. That isn't to say that all these numbers mean the toys will pose the same challenge as eachother! Some toys deviate a little away from their numbered sizes within a few decimal points, but it's still a clear enough demarkation for everyone looking for a toy of a certain size.
That's really all there is to it - an elegant solution to an industry-wide problem. But what can we say? We're enablers that just want to see your cunts wrapped around bigger and bigger toys every day, and we're shameless about it.
