Have you ever had acrylic nails done? It's expensive and doesn't look great, even if all the celebs have them, but it will give you a proper feel of how better longer nails look and feel! PLUS, you genuinely can't bite them because its plastic and secured with a lot of hard glue.
Had the presson nails, but they just feel awkward. I like my nails short, always hated the feeling of a buffer or whatever it's called, so I just kept biting.
I could have a worse bad habit. That's my justification.
