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.
