With these tip guides you get one sheet, this is set #1 which is the lightning shaped design. The sheet itself has 30 guide stickers on it. Let's have a quick look at how to use these, first paint base colour, make sure it is 100% dry. then:
Line up the stickers on the nail. Paint over the gaps, then remove the stickers immediately.
These stickers worked quite well and they were something different, I have seen a lot of chevron (review here) shaped ones recently as well as the more traditional French tip guide designs (review here). Nail stickers have gained quite a lot of popularity recently. They are quite sticky and stick to the nails even with a strong C curve to your nails.
Here are some nails I have done using these lightning shaped nail stickers.
Black and White
Something I would suggest is using the lighter colour as a base and then going over with the darker colour as this did cause me some problems with the black and white nails. Also be mindful as to which polish you use for going over the top with as it will need to be mostly opaque in one coat. These are from BornPrettyStore, you can see some of there new products here and what is most popular here.
This challenge has been going on for well over a year now, but the idea is there are three colours pre-picked and you find those three colours in your stash and use them in some kind of nail art. For the blue I used Max Factor's Odyssey Blue, the yellow Collection 2000's Sorbet and the red is ELF's Red Velvet.
