Protective sleeve?

Any way to get a protective sleeve for the tip (the insertable part) of the Only Key? I mean, every other USB-type device that I have has a protective sleeve, but the Only Key seems to not have one. I cannot find anything on your products page. Any suggestions? Or is the tip of the Only Key not easily damaged? Seems like a protective sleeve should automatically come with the key. Please let me know. Thanks

When you say every other USB-type device has a protective sleeve I am not sure what you are referring to. Every single USB security key on the market comes with no USB protective sleeve i.e. Yubikey, as there is no need to protect this part it is durable enough to be used for years with no protection needed.
