A bit of Trivia;
He owns spiked versions of pretty much every kind of accessory he owns.
He likes the look of 'em, but is embarrassed to publicly wear them. Yet, wearing them makes him happy, so sometimes when he's all alone and engaging in certain types of activities, he'll wear them around.
He gets ashamed of some rather odd things at times, but it ain't something he can really help.

And in case you're wondering!
His regular, non-spiked accessories are generally a bit looser and are made of stretchy, springy and somewhat velvety cloth.
The spiked ones are tighter and not as wide though, and are more rubber-y in terms of material.
The universal traits are that they're soft, stretch and durable! He's gotta get them past his arm-spikes after all~
