I recommend the peel-off base.

I recommend the peel-off base sold at Daiso for 2,000 won. While many brands sell peel-off bases, Daiso is the only place that offers one this affordable. You don't need to cure it; just apply it like regular nail polish, let it dry, and then apply a top coat over it. It's really great because it doesn't damage your nails. Try using a peel-off base that minimizes nail damage.
