I like Dashing Diva.

I've tried gel nail stickers and regular polish, but stick-on nail tips last the longest and are the best. I especially love Dashing Diva products because they really do last a long time. A great tip for making them last longer is to apply them before bed, sleep, remove any oil from your nails, and press them firmly into place; it really does make them last a long time. I highly recommend it!
