I've been consistently cutting my nail off with a knife while preparing meals, literally. The last time it took me three weeks to grow it back to normal size only to cut it again accidentally. So I decided to purchase this practice set from bornprettystore.com. Now I don't have to stop doing nail art even without my real nails.
I bought these 600 pcs of false nail tips for $4.57 and two display fingers, to attach the nail to, for $1.99.
To be honest, only a few numbers fit my nails but you can trim the sides easily with a nipper for the bigger ones. I like it just fine for practice but it's a little thick not to be noticed if you plan on wearing it.
The display finger is really helpful as well. I was worried at first since I'm only using double sided tape to attach the fake nails but surprisingly, it was easy to clean up afterwards. The size of the finger is also perfect enough to hold for practice unlike the small and thinner ones.
I've only used these a few times since purchase but I'm quite satisfied with it. It's also much better than practicing with nail wheels although that is cheaper.
