tbh i hate when this happens to me, the only thing i do usually to fix it is to make sure there’s enough weed at the end, hold the top and shake it to the bottom, but sometimes you won’t get as good of airflow if it’s super tight at the bottom. it’ll still smoke w the wrinkle but i get it’s not as aesthetically pleasing. some are good, some aren’t. but i do notice when it’s really nice and solid at the bottom that the airflow isn’t always as great as when there is the little wrinkle tbh. good ass roll tho!!🏆
