So this kit came with a buffer, a nail stick, an instruction leaflet,
a lamp,
a bottle of remover (acetone), a bottle of cleaner (rubbing alcohol),
a bottle of bonder (15mL),

a bottle of base/top coat (15mL)

and 5 polish colours (7mL; 0.24oz).

All-in-all a great kit, the sucky thing is at retail price it is more than $100 unless you can find it at Costco or some cheap warehouse like place.
So I am really getting into the gel polish, except for the prices of the stupid polishes.
Quo by Orly sells some 4.4mL (0.15 oz) bottles for about $10!

At Sally Beauty they had about 10mL (1/3 oz) bottles for about $15 which is getting more reasonable

and nailuv sells 15mL (0.5 oz) bottles for $10-15 which seems pretty good (if you don't include shipping). I know OPI has some gel polishes and I want to try those but I have to find them first... :P
Since we cure gel polishes under an LED or UV lamp (oh btw. all gel polishes can be cured with UV but not all can be cured with LED so make sure you buy ones that work with your type of lamp) sunlight can thicken the polish. This is why they are kept in opaque bottles (mainly black), to prevent sunlight from thickening and potentially ruining your beautiful, expensive polish.
