Who doesn't love a sea of colour? I would change my nails every night if I had the time!
I have always liked OPI's bottles with their sleek black lids (unless you get a crackle or other special which often have a pattern). The clear glass bottle allows you to see the colour inside and the brush glides on so I only have myself to blame when I miss my nail completely.
OPI has amazing colours and a HUGE range of products (including magnetic nail polish - what will they think of next!?!?!) with gorgeous names. In case you weren't already in love with that colour let's give it a name like 'Kiss me I'm Brazilian' to seal the deal.
Easy to apply and resonably long wearing the only thing that lets OPI down is the price. So perhaps more of a splash out rather than a weekly purchase (this coming from the girl who has a draw full of OPI)
However if you are going overseas duty free is your friend! They have great deals on OPI and better still..... If you or someone you know is going to america make them fill their bags as it is sooooooooooooooooooo cheap over there!!
O.P.I have such a fantastic range of colours I can never decide on what colour to choose when I purchase/paint my nails! It is so smooth and easy to apply and comes over just as easily. It doesn't smell that strong which I like as quite a few polishes I have smell quite strong. On the cons list I have the black onyx and it has been gluggy and really thick since the day I purchased it. Don't no what went wrong with that one but that is the only downfall, the rest is great :)
