shadesdragonit's basically just extra branding on the side, they want to make arguments that say they're optimized for gaming specifically not just computing but you can tell from images on their store that it's all the same, that said I have a pair of mlg's and they're wonderful if you're in front of a screen all day, I got mine half off so for 40$ I'm thinking about getting an extra pair just to switch up styles.
shadesdragonPPK is a frame name and is a nod to the Walther PPK from James Bond movies. MLG stands for Major League Gaming. We have a partnership with them and make a couple frame styles with their logo on it.
