I have never seen a fingernail mask before, and thought is may be something new to try out.
They come in two strips of five which you tear apart in to thimble like caps for each finger.
These were hard to work with, getting them all on to each finger while wearing them. They kept falling off as they were loose fitting. Because of the fit I didn't find they pushed against the nail enough to moisturise the nail without pushing them against my nails.
Before and After;
Not something I found was useful, they didn't stay on the nails and as soon as you moved your fingers they fell off. The suggestion said leave on for 30 to 60 minutes which was difficult. They did hydrate the finger tips and nails but I imagine that was down to the high quantities of glycerin. They would have worked better if the caps were elastic or something similar so it gripped to the fingertips.
The lipstick is a semi matte finish and is a deep red colour. It wears well and I really like the formula of these lipsticks, because they are semi matte in finish they last a long while and isn't something you have to constantly check up on, which when wearing a red lip is especially important.
