Okay so the item L33T Gamer has a minor issue in my opinion. It may look right as you equip it, but it mirrors outside of the customized your avatar screen. Is this intentional?
It depends which way your avatar is facing. It will look mirrored when your avatar faces one way, but then when you post and your avatar faces the other way, it'll look like it did in the dressing room.
That's because your avatar is facing towards the right currently. If you were to post twice now your avatar would be facing the left and it'd look the same way it does in the dressing room.
It's how all text based items work
They stay the way they are facing until your avi itself flips based on posting and such
Some have hidden features depending on which way you're facing, others stay how they are and appear backwards
