The OPI envy express kit has the nail envy and the strengthened polish. It also has the drip dry and a dropper. I actually really like the polish. It is really hard and give my nails a nice shine. It even stood up to me planting a garden. The drip dry actually works. 1-2 drops and it was dry to the touch within a minute. Would I buy it again. Yes and no. No I would not buy the little kit. I will. buy the full size version of all the products instead.
