Lo smalto (per unghie) - Nail varnish
I'm not someone who wears smalto very often, purely because I'm too lazy to sit there and patiently put it on. These two were birthday presents, so I feel obliged to use them!

In most cases the masculine definite article is il (l' is used before a vowel), but for words that start with certain letters, lo is used for ease of pronounciation. The 's+ consonant' combination at the beginning of the word is one of these, another example of this is the 'sh' sound in champagne, or sci.
