I've been getting into nail art recently as part of my makeup routine, so my item would be this awesome tool set!
I cant think of any ready kits, but you could put one together for her? Ger her some nail brushes, the really thin ones for decorating, then dotting tools, as well as strips and tape, stickers, aaand some other stuff. These are all the things I have :)

a little drier may come in handy too, as nail art is layered and can take a long time to dry http://www.amazon.com/PROMOTION-USpicy-SEASHELL-Portable-Manicure/dp/B005WQB6G4/ref=sr_1_1?s=beauty&ie=UTF8&qid=1417152565&sr=1-1&keywords=nail+dryer
As well as one of these quick dry drops or sprays

Shop around and you'll find them for lower prices.
If you have time, buy them on eBay, that's where I always get them. They get shipped from Chine or Hong Kong and super low prices. I've bought 5 nail dotting tools for 1-2$, including shipping, and lots and lots more. A 12 wheel of nail decals, stickers and whatnot, for 99 cents.
Dotting tools, tape, and brushes are cheap on Amazon. Here is dotting tools and brushes together. And some tape. Here are some tip guides
For straight lines I'll use tape. Other wise I draw them with thin brushes. For the chevron look I'll use those tip guides.
I know there are better items out there, but these are what I use.
