[by2ky]

Where can i find good quality and cheap hard chewing gums? I don't want to be scammed by some dropshipper or start chewing on some pure bottle cap plastic chewing gum slop?

and also, is this chewing thing for jaw even real or just copium

yeah it helped me, if you chew constanly everyday for like 30mins. I dwa change in my ramus lenght, idk if this just my maszeter size but my side profile looks much better. And just buy any gum without sugar
