@Barbara Gregory Here's my honest take for right now until I make the actual class recording. Test them yourself as much as you can. Full cover nail tips can be made from all sorts of plastics so they can be bendy, brittle, they can tear, break, and THEN when you mix an adhesive with it, it changes it again chemically so there's a LOT of variables. SO If you're putting them on clients and having them return in 2-3 weeks and removing or filling, make sure you test them yourself (or put them on a few clients to test for you). Ours at Wildflowers will work, Apres obviously, there's LOTS of brands out there. If you're REALLY getting into it and need to buy as cheaply as possible, you'll have to cut out the middle man (wildflowers or apres) and source yourself. You can do this on amazon, aliexpress, temu, I mean you can go nuts, they're all made in China and shipped stateside. You just have to find a steady provider for yourself once you find one that fits your business.
