These are the products I show you in the video, I have also put a link to where I bought them, but many other sellers do these products, so have a look around to find the cheapest you can! New listings are coming on all the time :]
Nail Art Brushes - I bought them here, £2.49 shipped.
Rhinestones - I bought them from a seller who sold out, so search here for the best value ones. I got mine for 99p without shipping, so it would have been £1 odd after shipping.
Different Shape Rhinestones - I bought them here, 99p Shipped.
Dotting Tools - I bought them here, £1.68 Shipped.
GCOCL Plates with Hello Kitty Plate - I bought them here, £6.99 shipped.
Fimo Canes - I bought them here, £3.27 shipped.
Make Up Sponges (I use these for gradient nails) - I got these from Home Bargains for 79p, which is a shop in the UK. I am sure any supermarket or discount store will have something like this.
Remember, these are just ones I have bought from, you can always have a look to find better bargains! :]
