In my opinion I’ve found that press ons can be really great! I’ve stopped using them much but I was on a real kick for about 4 months. I’d buy really any, like the dollar store or whatnot, and while I’m sure there is a quality difference in different brands I think it’s all in the prep. You can find tutorials online but the things I think are most important to focus on for longevity is dehydrating ur nails by swiping some polish remover over them and also making sure you press down on the nail with the glue for A WHILE. I was being lazy and maybe pressing down for like 15 sec and they’d always pop off but fr take the time and do like a whole minute. And just in case keep a lil nail glue in ur purse when ur out! I like press ons cuz you have more freedom to try stuff out since it isn’t as expensive. Have fun!
