I was granted an opportunity to try the 'Steel of the Night' colour of Sally Hansen stick on nails, which is similar to a French manicure, but with grey/silver tips. In case you were wondering, this is really nail polish. It even smells like nail polish.
To begin with I found the instructions slightly confusing, fortunately there are 16 tips in the box (two to one strip) so if you waste a one or two (as I did) it won't be a problem. Once I got going I found that this skill was much easier to learn than with a bottle of nail polish and the finish resulted in beautiful clean cut lines. I also really liked not having to wait for the product to dry because often when painting my nails I start doing something else and ruin them.
So overall I really liked this product and though it took a little getting used to, it was easy to use. One thing I will say is that you end up with a lot of rubbish at the end of it. But for a professional looking finish the product it worth the price.
I found these fiddly the first couple of times, but have stuck with them and now prefer to nail polish. I find that if you lay out the ones you are going to apply, it makes things simpler. And i tend to go for strips that are slightly too big and file down the sides too, ensures full nail coverage. Great for occasions when you want something a bit different, and dont have time to visit a salon.
Tips: always ensure nails are clean before applying. and add a top coat afterwards to provide better staying power
